Every March some 50,000+ people descend on my hometown of Austin, Texas to check out the latest in music, film and interactive tech in a giant marketing orgy called South by Southwest. As an Austin resident, it's the kind of thing where you either want to attend the event, or GTFO.
It's one of the few times of year when I use Twitter on a regular basis. For the rest of the year, I use Twitter to post random thoughts and short quips. I have set up the "Twitter for Facebook" application to re-post all my tweets to Facebook, so that I can share those self-indulgent remarks with my friends & family in a more directed manner.
