I just realized that my yahoo profile is now over 10 years old! I apparently created it on February 12, 1998, and while I know that I had AOL at home before that for perhaps around a year, I can't find any indication that they provide account creation dates anywhere in their system. (And back before AIM was properly integrated, I had to switch from ckdake to theckdake when we canceled AOL and didn't get to switch back to ckdake until perhaps college?)
Before AOL, I got online once or twice at a friends house, but I know my first experience online was at the 99X booth at some olympic experience thing at the 1996 Atlanta Olympics. They had a web browser, I typed in "games" in the address bar and alas, couldn't get to any games. Needless to say I didn't realize that the internet was good to have until later.
In 1999, I purchased my first domain name: ithought.org (for $70 a year or something stupid expensive from Network Solutions) and it's still the one I use for all my servers. ckdake.com finally showed up in 2004.
Things sure have come a long way in ~12 years!
