I'm starting to get excited about SXSW 2003. I've been busy doing some coding for SXSWblog. There's a new photo exchange and notes exchange that's integrated with the site membership. (The notes exchange is also now Trackback-aware, so anyone can post to their weblog and trackback specific conference events.) Working on this has me thinking about other potential conference-related collaborative projects. I'd like to see something along the lines of geourl meets a weblog—tracking geographic locations of attendees through time. Imagine being able to say: I'm here now, I was there, and I'm going there through a web interface. It would be so much easier if everyone had a WiFi-enabled GPS and could "post" spots to their location-blog.
