I'm the guy who coded it. (For the most part - there was, of course, assistance from other people.)
However, this is my weblog/journal, so I won't do much discussion of it here. If you've got questions about FOAF or anything like it, your best bet is to check out ljfoaf (http://www.livejournal.com/community/ljfoaf/, for those of you not familiar with LiveJournal). I maintain the community, and will pay much closer attention there to any kind of FOAF content than here.
If you need to contact me, you can do so at firstname.lastname@example.org, but really, your best bet is to just check out the ljfoaf community. You might find a lot of information there that you wouldn't otherwise know.
