Trend: Social Networking: 43 Things

43 Things
One way to get to know people...
http://www.43things.com/

per Wikipedia:
43things.com is a social networking site that is built on the principles of tagging, rather than creating explicit interpersonal links (as seen in Friendster and Orkut). Users create accounts and then list a number of goals or hopes; these goals are parsed by a lexer and connected to other people's goals that are constructed with similar words or ideas.
