It doesn't take much to keep the site alive -- I've just had to transition it across hosts a few times, but otherwise it just continues to sit there. There is a tiny amount of revenue that still comes through it, but mostly I just like the idea that it still exists, and I think others do too. I suppose I also don't want to let go of my fifteen minutes of fame. :)
These days, the thing that most impresses my nephews is that I posted the second ever video to YouTube (college roommate was a cofounder). I have long since lost control of the channel (it was taken during a transition from old YouTube accounts to Google accounts when someone guessed the simple password). Since hacker news can sometimes be the support site of the internet I'll throw it out there -- if anyone has a contact at YouTube that can return the channel to me, that would be awesome. I imagine it is long-since gone.
