I think the first thing I wrote was Nov. 1st, 2004. And you may have been the very first person to give me feedback. First or second, I don't recall. I may have saved a printout of our exchange! I was putting feedback into binders for a while, and I think I've kept some of it. :-)

ETA: I just found an early LJ interaction where you refer to yourself as my first feedbacker, so it must be true!
