25 years! 1991. It would be 2.5 years before I built my first website, 4 years before I co-founded Austin Freenet, and 5 years before I sold my company, Go Media, to Excite. I and my staff were using AOL, and were trying to get clients to do the same. Getting access to the real Internet was pretty damn exciting. My first email came from Steve Swartz. For the first week or so, I printed out every email (there were only 5 or 6).
A few weeks later Go Media became the first company in Austin to install ISDN. At least that's what the guys hooking it up said.
Good times. :)
