"OK, this is just deeply cool. Conferenceer is a SXSW Interactive-centric social networking app and content aggregator with several great features. Post a profile on the site, then browse the list of panels. You can add a panel (or a day’s worth) to iCal, follow the feeds of presenters on the site or in your favorite newsreader (though OPML downloads) and create XFN-ish lists of attendees you’d like to keep in touch with."
