Cool FOAF things

FOAF (Friend of a Friend) is ...a way to describe yourself -- your name, email address, and the people you're friends with -- using XML and RDF. This allows software to process these descriptions, perhaps as part of an automated search engine, to discover information about your and the communities of which you're a member. FOAF has the potential to drive many new interesting developments in online communities.

Plink (People Link) is like a kinda techie/underground version of Friendster and has links to cool widgets like foaf-a-matic – a javascript application that generates your very own FOAF file from a web form.
