I actually backed into this biz -
Was selling cars (and had for years). This Internet thing pops up - so I decide to check it out. Had a direct line to the heads of Autobytel back in the day to help with selling cars online.
My store didn't have a website and they wouldn't pay to build one. So I went searching on How to Build one on my own. In about 20 seconds I was reading a Netpond thread.
And since my office was closest to the door, and furthest away from the managers, I took the liberty of pursuing this further.
Though I still think KK or one of you people I know paid for my 1st sale

(condomfh - no less)
For quite few years it was simply a hobby that paid for vacations, TV's and stuff like that.
Now it pays the bills.
