Our recent coverage of trends in the first half of 2010 have not fully touched on Facebook. The dominance of the world's most popular online social network has gone beyond being just a trend. It has become much bigger than that. This week alone we have posted about use cases for Facebook's OpenGraph as well as the introduction of OpenGraph for the mobile Web.

ReadWriteWeb has kept a close eye on not only the latest innovations of Facebook, but also on extensive privacy concerns, as well as what happens when you try to cancel your account. These 25 posts highlight what's trending in the first half of a busy year for Facebook.

Of these 25 posts, which do you think were the most significant? Please tell us in the comments below.

  3. What Happens When You Deactivate Your Facebook Account

  4. Last night I met a man who walked to the edge of the cliff and nearly deactivated his Facebook account. He took a screenshot of what he saw after clicking the "deactivate my account" link on his account page - and it is pretty far-out. That man considered quitting Facebook because it was having an adverse emotional impact on him and I'll spare him and his contacts from posting the screenshot he shared with me. I have posted below though a shot of the screen I saw when I clicked that button myself. Check it out. I bet you haven't seen this screen before, have you?

  5. How to Delete Facebook Applications (and Why You Should)

  6. To the end user, these changes may sound overwhelming and even scary. But there is something very easy everyone can do to minimize their risk and that's delete the Facebook applications you no longer use.

  7. The 3 Facebook Settings Every User Should Check Now

  8. The tool, a dialog box explaining the changes, appeared at the top of Facebook homepages this past month with its own selection of recommended settings. Unfortunately, most Facebook users likely opted for the recommended settings without really understanding what they were agreeing to. If you did so, you may now be surprised to find that you inadvertently gave Facebook the right to publicize your private information including status updates, photos, and shared links. Want to change things back? Read on to find out how.

  9. Facebook's Zuckerberg Says The Age of Privacy is Over

  10. Facebook founder Mark Zuckerberg told a live audience yesterday that if he were to create Facebook again today, user information would by default be public, not private as it was for years until the company changed dramatically in December. In a six-minute interview on stage with TechCrunch founder Michael Arrington, Zuckerberg spent 60 seconds talking about Facebook's privacy policies.

  11. The Man Who Looked Into Facebook's Soul

  12. This Wednesday, Warden will make Friend, Fan page and name data from hundreds of millions of Facebook users available to the academic research community. It's a move that Facebook has to have seen coming, a move that many in the data-centric community have been calling on the company itself to do for years, and an event that's been complicated by Facebook's recent privacy policy changes, which have muddied the waters of right and wrong but rendered even more data available for outside analysis.

  13. Why Facebook is Wrong: Privacy Is Still Important

  14. Has society become less private or is it Facebook that's pushing people in that direction? Is privacy online just an illusion anyway? Below are some thoughts, based primarily on the pro-privacy reactions to Zuckerberg's statements from many of our readers this weekend. Though there is a lot to be said for analysis of public data (more on that later), I believe that Facebook is making a big mistake by moving away from its origins based on privacy for user data.

  15. "How Do I Delete My Facebook Account?" A Fast Growing Query

  16. Google Suggest, the drop-down box that offers suggested search query completions based on absolute and recent upticks of popularity, now guesses that if you start typing "How do I..." that you'd like to know how to quit Facebook.

  17. Facebook's High Pressure Tactics: Opt-in or Else

  18. Facebook users who choose not to link their user accounts to Facebook's public Pages are ending up with blank profiles containing no information at all. If you haven't experienced this problem, it's probably thanks to the somewhat high-pressure tactics Facebook is using to get you to accept these changes.

  19. Diaspora Project: Building the Anti-Facebook

  20. Why can't privacy and connectedness go hand-in-hand? That's the question being raised by those behind the new Diaspora project, an ambitious undertaking to build an "anti-Facebook" - that is, a private, open source social network that puts you back in control of your personal data.

  1. Facebook Open Graph: The Definitive Guide For Publishers, Users and Competitors

  2. Facebook's vision is both minimalistic and encompassing - but its ambition is to kill off its competition and use 500 million users to take over entire Web. Whether we like it (pun intended) or not, we have to understand what this move means. It impacts users, publishers, competitors and, of course, Facebook itself. In this post, we summarize what Facebook announced and ponder the impact this will have on everyone. The Open Graph is a set combination of publisher plugins, semantic markup and a developer API.

  3. "Likejacking" Takes Off on Facebook

  4. Security researchers are warning of the newest Facebook threat, something they're calling "likejacking," a Facebook-enabled clickjacking attack that tricks users into clicking links that mark the clicked site as one of your Facebook "likes." These likes then show up on your profile and, of course, in your Facebook News Feed where your friends can see the link and click it, allowing the vicious, viral cycle to continue.

  5. The Internet is Hard

  6. Earlier today, we had a runaway hit of a post that went viral within a few hours, getting unbelievable pageviews and hundreds of retweets and comments. The trouble was, it wasn't because of the post's content. Due to some interesting SEO magic, the post was one of the first search results for the term "Facebook login." As a result, hundreds of confused readers bombed us with angry comments about how much they hated the "new Facebook," a.k.a. our Facebook Connect comment login.

  7. How to Trick Users into Liking Facebook Pages They're Not On

  8. Yesterday, Facebook launched a new widget called the "Facebook Like Button," which, simply put, brings the Facebook like button to the entire Internet. Website owners can implement the new button on their site using a small bit of code. In fact, you don't even have to be a developer to make your own like button - there's a little wizard that generates the code for you. Then it's as easy as copy-and-paste to get the button onto your site. However, there's a small problem with this new, easy-to-use new tool: it's possible to trick users into liking anything - even pages they've never visited!

  9. Is the New Facebook a Deal With the Devil?

  10. Facebook blew people's minds today at its F8 developer conference but one sentiment that keeps coming up is: this is scary. The company unveiled simple, powerful plans to offer instant personalization on sites all over the web, it kicked off meaningful adoption of the Semantic Web with the snap of the fingers, it revolutionized the relationship between the cookie and the log-in, it probably knocked a whole class of recommendation technology startups that don't offer built-in distribution to 400 million people right out of the market.

  11. More Web Industry Leaders Quit Facebook, Call For Open Alternative

  12. Tonight leading video podcaster Leo Laporte announced that he's closed his Facebook account and made a financial donation in support of Diaspora, a project working to create an alternative social network outside of Facebook's control. Laporte said he was convinced to make the move by a post written by entrepreneur Jason Calacanis, in which Calacanis called Facebook a "monster" and called for users to throw their support behind OpenID and advocates of distributed social networking as open as the internet.

  13. XAuth: The Open Web Fires a Shot Against Facebook Connect

  14. The gist here is that XAuth will make it easier for sites around the web to find out what social networks you are using, let you log in to those easily, access your permitted information from those networks in order to better personalize your experience on their site and easily share their content back into your social network. It's like Facebook Connect, but for every other social network.

  15. Facebook's New Policies Make Harassment Easy

  16. North Africa has become a testing ground for a new sort of online harassment, and ReadWriteWeb is in the middle of it. Groups of Islamists are using the proliferation of Facebook's public pages to single out users they consider ideologically unorthodox (a broad category indeed by their definition) and then using Facebook's public ban process to stop their mouths.

  17. The Half Truths of Mark Zuckerberg

  18. Today's changes were good for users concerned about privacy, but Zuckerberg's tone on the call was odd. He said a number of things that seemed of questionable...truth. Those were: that settings weren't changed arbitrarily when all this began in December, that the changes weren't driven by advertising and business concerns and that Facebook makes its decisions based not on criticism but on metrics or its belief in what the right thing to do is.

  19. CONFIRMED: Facebook Gets Faster, Debuts Homegrown PHP Compiler

  20. Facebook officially announced the project, titled HipHop, this morning and confirmed that it would be released as open source this evening. Facebook will be hosting a talk at 7:30 PST with PHP developers to get into the specifics.

  21. Facebook Granted Patent on the News Feed

  22. Nick O'Neill at AllFacebook found the patent first and says it could be "one of the most significant social web patents" in a decade. If all algorithmic ranking and delivery of social activity updates to social network users falls under this patent Facebook applied for in August 2006 (one month before it launched its controversial Newsfeed) then there's going to be a whole lot of trouble for sites all over the web.

  23. How US Government Spies Use Facebook (UPDATED)

  24. The US Department of Justice this week released slides from a presentation deck titled Obtaining and Using Evidence from Social Networking Sites. The document was released in response to a Freedom of Information Act request by the Electronic Frontier Foundation (EFF).

  25. Facebook and the Future of Free Thought

  26. So Facebook is the web's most popular subscription-enabled place to read news; be it from links shared by friends or by becoming a Fan of news organizations like Facebook is now encouraging. That doesn't mean that Facebook is yet a better news-reading service than dedicated RSS readers are. But it has certainly caught on as a way to read news far better than dedicated news-reading software has.

  27. The Facebook Backlash Has Begun...

  28. The knee-jerk reaction has begun. Friend after friend after friend is posting the same chain-letter-like status update with simple directions on how to opt out from Facebook's new sharing capabilities. It's spreading like wildfire, but we have to ask - has anyone considered the up side to any of these changes?

  29. Privacy, Facebook and the Future of the Internet

  30. Today is the 3rd annual international Data Privacy Day and a whole bunch of companies are listed on the organization's website as participants. Google, Microsoft, even Walmart. Facebook is not listed as a participant and has stirred up a lot of controversy with changes to its privacy policy lately.
