This entry is for bringing up these suggestions. With the huge number of RDF resources on the web, there's a giant map of possibilities that could be searched for and used to describe LiveJournal users - the ones included are just a start.
Leave comments here for expansions you'd like to see for LiveJournal's FOAF support. Supporting your arguments with links so I can understand what you're going to use it for is good - as the original and main coder of LiveJournal FOAF, I'm going to be the one making the changes, most likely.
Convince me. What information do we need next?
