I recently posted up a listing and description of 40 social bookmarking sites. Little did I realize what a small tip of the iceberg I was describing!
In commentary to that post, I was directed to Baris Karadogan’s posting of Web 2.0 Companies, which contains a fantastic compilation of 980 specific sites with links. I began reviewing user comments and discovered, possibly, that the original compiler of this list is Bob Stumpel of the Everything 2.0 blog. It is hard to provenance the origination of the list, but Bob is active in assembling long lists of updates. Boris’ is more attractive with embedded live links.
Both of these reference lists have organized the sites into about 70 different categories, a sampling of which shows the diversity and innovation taking place:
The next useful step for some enterprising soul is to provide more commentary on each site and better describe what is meant by each category. Perhaps someone will step forward with a wiki somewhere.
Likely few of us have the time to look at all of the sites listed. But I am slowly sampling my way through the list, checking out the variety of approaches being taken by clever innovators out there. While some of the links are dead — not unexpected in such a nascent area or with such a long list — I’m also seeing alot of clever ideas.
This listing is a useful service. If you know of a missing site, please suggest it to one of the two compilation sites. And, I do hope someone takes authoritative ownership of the list and proper attribution is given where appropriate.
