Back in 2005, I took a week off work to attend SxSW (more for film and music than the interactive). At the time I blogged:
Yesterday at work, people kept wishing me well for my vacation. It was strange because I don't feel like I'm going on vacation. I feel like I'm switching to one of my other careers full-time for a week. Attending all three streams of SxSW (film, music and interactive) for a total of ten days isn't what I'd call a vacation. At least as fun. But not "vacation".
