Technology Review has an article on a new software application called Boxxet that allows users to rate search results with the intent of improving relevence, timeliness, and usefulness of search results.
It sounds like something Google automated in the original PageRank™ algorithm, but we will see.
The article also mentions Microsoft's ongoing development of Windows Live in an effort to attract users.
It's amazing how many sites use some sort of social networking and consequently how competitive this area has become. Not sure if anyone has an authoritative list of how many such sites exist; but here's someone who is trying to keep up a Social Networking Services Meta List.
Not sure how successful a meta list will be given the continued specialization of such applications. For example, I noticed someone in the comments had noted that the meta list didn't include HAMSTERster.com a virtual hamster and gerbil community.
The more I think about it I realize I don't know what social networks are, at least in terms of Web 2.0 speak.
