Welcome!
This community is geared towards discussing uses of, applications of, and nifty things about the LiveJournal Friend of a Friend information. Since I wrote most of the code for this feature, I'm probably going to be writing most of the documentation for the time being - my goal is to have a centralized resource for those people who are using the feature for all kinds of nifty things to share tips and tricks.

If anyone needs to contact me, my contact information will always be available in the community user information. I haven't had too many problems with trolls in communities I maintain in the past, but I will deal with situations as they arise, as best I can.

For more information on what FOAF is, check out http://www.foaf-project.org . The people there have put together a useful informative site describing what the spec is and what it does.

Welcome to the community!
