Joi Ito’s recent entry sparked my interest in FOAF—I missed the meme the first time around (well, I saw it but I just didn’t care at the time). Quite coincidentally, I stumbled across this Webmonkey article covering metadata this morning as well. I’ll keep looking into this. If you have any important evaluations about this technology, please leave a message in the comments. I don’t get the value in this since it seems like XML blogrolling.
