I'm kinda impressed that in the four days I've been here, the site has gone from a bit slow and clunky to smooth and reliable. I guess in part that's just how computing speed has improved so much over the years. Even VPSes are cheap. We're not on a 400MHz Pentium II with spinning rust any more, where the idea of going to many thousand users in a short time was clearly impossible. These days things can scale upwards pretty quick.
