As a Web (2.0) consultant and analyst (about me), I track a variety of market segments and products. Luckily for me, nowadays I don't have to do as much grunt work on gathering high level product data as I used to. There are a plethora of product lists and data about web 2.0 companies on the Web now, unlike 12-18 months ago when I had to track it all down myself. Of course my job as a researcher and analyst is to go much deeper than the high level product data - I then need to turn it into practical insights, recommendations, knowledge, etc.
Anyway here is (in no particular order) a list of the web 2.0 lists and other helpful product data that I've found on the Web. I encourage you to add other sources in the comments.
- Ask the eConsultant - seriously impressive list of web 2.0 companies, categorized.
- Techcrunch product review list - organized by company name; would be great if also categorized into market segments.
- Virtual Karma "Complete List of Web 2.0 Applications" - despite the title, far from complete. But scan the comments too.
- Sacred Cow Dung's Everything Web 2.0 - fantastic list and nicely categorized.
- Bob Stumple's list A-K and L-Z - this is where Sacred Cow's list is derived from, I think.
- Map of the Web 2.0 World - not comprehensive, but has interesting and unique categorizations.
- Mashable weblist - Pete Cashmore's mini-blog "featuring concise, opinionated reviews of Web 2.0 companies". Would love some high level categorization wrapped around all the reviews.
- Map of RSS Vendors (categorized) - this is my own effort, helped immensely by the people who added to the wiki.
- categoriz - nicely categorized list, but not much context around each entry.
- NEOBinaries - well-designed, well categorized and feature rich web 2.0 company/product resource; eats the 2.0 dogfood, with user reviews and ratings, etc.
- Buzzshout - makes heavy use of tag cloud for categorization. Also has reviews and user ratings.
- ProgrammableWeb - the list for mashups, complete with graphs and stats analysis. This is in many ways what I would love to see done on the web 2.0 lists.
- The Museum of Modern Betas - I'm told this is a good list of beta products (and what isn't beta in this era of the Web). Unfortunately I've never been able to see it, because of access issues with the domain.
- Library Clips meta list and Saul Weiner's list - John Tropea and Saul also have the 'list of lists' thang happening.
- Emily Chang's eHub - Another excellent resource and is categorized too.
- Web 2.0 Innovation Map - not really a list as such, but a Google Map of 2.0 startups.
- Web2List - the name says it all!
- Listable - organized by popularity.
- Web2.0Slides - "a self-running slide show of over 1,400 of the best Web2.0 sites."
- Office 2.0 Database - nicely categorized table.
- I want to: - organized by user-focused tasks, e.g. "Communicate with other people; chat, email".
- WWWhat's new? - Spanish list which looks pretty comprehensive.
- Web 2.0 in the Enterprise - wiki by Jeff Nolan with excellent list of enterprise apps.
I'm sure there are more web 2.0 lists out there which I've forgotten to mention, so please add in the comments and I'll update this post as they come in.
Update 7 May 06: Added more lists based on comments. Will do more updates as required.
