"FooWho  is a new site that aims to deliver items that are interesting to you, based on your personal preferences.\nThis functions in two ways: you fill out a personality profile so the system can know more about you and your interests, and you submit items to the site.  This works similar to Digg, with a social matching component thrown in there.  For instance, if you're looking for a useful how-to video on a particular subject, you can perform a search.  The results you get are based on relevance to your query, and enhanced be the fact that they're provided by other FooWho users who share the same interests as you.  It's taking social bookmarking and personal recommendations to the next level by showing the stats of all the items submitted to the site.  This gives you more information on the user as well as the submission, and even encourages you to browse the site on a bit of a deeper level.  You can add items to your watch list, which automatically includes comments watching as well. \nEach item can also be voted on, either up in ranking, or down.  It looks like FooWho is taking this voting system rather seriously.  If you submit a duplicate item, you can be penalized by losing points, and thus losing your rank score.  The more you submit items that are voted up, the higher your ranking goes.  This ranking works on a 5-star scale, and once you've earned two stars, you can begin participating at a more authoritative level throughout the site.  This means you'll be able to edit the items of other users, which is supposed to ensure the quality of content on the site, while also recognizing trusted users. \nAnother site that will match you up to other users based on your personal preferences is Qubox.\n"^^<http://www.w3.org/2001/XMLSchema#string>
