I usually adopt technology slowly on this site. I’ve never put up a FOAF file, and my bookmarks are not available in OPML. I don’t support trackback or pingback. I’m still not even entirely sure what Atom is. But I’ve decided to jump on the LOAF bandwagon. I think it’s the kind of universally useful technology that will find application on lots of sites. And its elegantly minimalist specification ensures widespread adoption.
