Eventually I laughed and said "Well, no one in this room will ever work on a two-letter domain again. That's probably reason enough. At least we get to say we launched one."
8 years later I still think about that day. I've had a pretty wild career, but yep, I doubt I'll ever get to build another TV.com.
Anyways, that's my tiny anecdote about a two letter domain! Worked with a lot of good people on it and still work with some of them. It's a pretty different site now, but right out of the gate it was huge and had tons and tons of community contributions to its episode guides, storing everything in a nice structured data style. These days all I think is... man, we could have done so much more with it (we should have put an API out for the data at least). From what I understand, Google's sidebar related data search results have slowly been biting at into the traffic of large wiki repositories like TV.com and IMDB over the past couple years.
