You just feel, when you’re around people developing the best new web software, that something new is happening, and that many strands are coming together.

I signed up for Gowalla just a few days ago, and though the usefulness of it beyond a fun social network is a bit lost on me, the potential it has is certainly obvious. (Perhaps part of Gowalla’s usefulness being lost on me has to do with the fact that I only have a handful of friends with iPhones, and of them, only a couple were nerdy enough to sign up for it.)
