Questr started out as a small side-project. I had never designed a mobile application, and Jeff had never built one. Now we have. We might do more stuff too, but this is how we spend our Sunday afternoons. That and playing Zelda. :)
I design things. I also sing, dabble in art stuff and have gotten hooked on the Dresden Files book series by Jim Butcher. I've been described as having a blatant disregard for authority.
I build things. I've only recently discovered Twitter. Sometimes I make YouTube videos about games, television and stuff I find interesting.
