recommendation technologies and in this post we give an overview of the different approaches - including a look at how Amazon and Google use recommendations. Wikipedia notes that recommendations are generally based on an "information item (the content-based approach) or the user's social environment (the collaborative filtering approach)." We think there's also a personalization approach, which Google in particular is focused on. We explore some of these concepts in this post.We're running a special series on

Pandora or Slacker Radio are indeed nothing else but highly sophisticated music discovery engines. In this post, we look at the different approaches behind some of the most popular music recommendation and discovery services.Thanks to MP3s and the Internet, we now have millions of songs readily available to us with the click of a button, but, paradoxically, this has often made it even harder to discover new music to listen to. Every online music store and every social network that focuses on online music, however, now features some kind of music recommendation system, and some services like
"Social media" was the term du jour in 2008. Consumers, companies, and marketers were all talking about it. We have social media gurus, social media startups, social media books, and social media firms. It is now common practice among corporations to hire social media strategists, assign community managers, and launch social media campaigns, all designed to tap into the power of social media. But social media today is a pure mess: it has become a collection of countless features, tools, and applications fighting for a piece of the pie.
a report this week that highlights eight up-and-coming mobile technologies which they predict will impact the mobile industry over the course of the next two years. According to Nick Jones, vice president and analyst at the firm, the technologies they've identified will evolve quickly and will likely pose issues that will have to be addressed by short term strategies.Analyst firm Gartner released
Cloud computing may have been one of the biggest "buzzwords" (buzz phrases?) of this past year. From webmail to storage sites to web-based applications, everything online was sold under a new moniker in 2008: they're all "cloud" services now. Yet even though millions of internet users make use of these online services in some way, it seems that we haven't been completely sold on the cloud being any more safe or stable than data stored on our own computers.
This week featured the second annual International Data Privacy Day. Though data privacy is a big issue these days - it's not a whole lot of fun to think about. We offer in this post a list of four things you should make sure to know about regarding privacy, including some pointers to discussions of how the privacy situation today is more complicated than a traditional approach to privacy protection may allow for. We're not going to focus on how to get your tin foil hat to use PGP encryption, we've got a short list of things that all of us realistically should know about for a baseline of online privacy awareness.

What blog search engine should you use? That depends on your needs.
In order to join a conversation, you've got to be able to find it first. Three years ago "blog search" was expected to be a booming industry, startups left and right developed different technologies and more than a few raised millions of dollars to help users search the part of the web made up of blogs. These days no one thinks consumer-market blog search is a serious business, but many of us still have a need to limit searches to blogs. What should we do? ReadWriteWeb offers some recommendations and an assessment of the state of the industry below.
OpenID has shown a great deal of potential. But that potential has often been hamstrung by the series of hurdles through which OpenID users have been required to jump in order to use their credentials. When Facebook Connect entered the distributed digital identity fray, those OpenID usability problems came into stark relief. Now, Google and Plaxo have responded with a new workflow for OpenID logins that simplifies the process and improves the usability - by adding OAuth and the Google Contacts API to the mix.As a concept,
towards a real-time experience on the web, RSS is starting to show its age. To update your subscriptions, you have to regularly poll these feeds.

The newest service that tries to tackle this problem is Notifixious, but as Notifixious founder Julien Genestoux explains, a lot of problems still need to be fixed before ubiquitous real-time notifications can become a reality.RSS feeds have become the backbone of the Web 2.0 movement, but as we are moving

The Innovator's Dilemma, Professor Clayton Christensen of Harvard Business School describes the theory of how large outstanding firms can fail "by doing everything right." The innovator's dilemma, according to Christensen, affects companies whose success and capabilities can actually become obstacles in the face of changing markets and technologies. There is no more important an issue on the agenda of top management than driving innovation. In this post, we'll review the evolution of "innovation management" and how social media has a significant role to play. This is one area where social media can "move the needle" for large enterprises and help them change the very nature of the firm.In his book
