I'm using the SXSW Conferenceer application to plan my SXSX schedule.
This site is great because I can follow what Drew Olanoff is attending and then add those sessions that I think I'd like directly to my iCal calendar.
The SXSW site isn't easy to use for browsing. This way I can choose my sessions based on the thoughtful and extensive research of Drew. We've got things in common and we share the same interests.
Follow the sessions I'm going to at SXSW and the parties I'm going to at night.
