Well, if you want to go all Genesis, sportspages.com (now gone, I believe) begat sportsjournalism.com #1 which begat the present incarnation.
The original Sportspages.com, started by a guy named Rich Johnson, was a kind of a clearing house for what he considered the best articles/columns of the day. I think he ran into problems when he opened a message board without anyone having to register. Anonymous was a very popular id at the time.
Can't remember why it was shut down but I think Sandy had something to do with it.
Some of the originals (21, for one) might remember the details more clearly than me.
