I started following the forums on Infoworld's site to be educated and entertained, in that order. I saw that the active posters just blew the doors off me when it came to overall technical knowledge when I compare myself to them. They still do today. I've tagged along from IWETHEY to here, have learned quite a lot from the people here, and started contributing when possible by asking questions and giving info where I could help out. Give or take a couple of very mild arguments, I visit daily because I want to be here, reading, posting, learning, and having an overall good time.
While the sentiment about "business" taking all of the fun out of computing is right on (remember how much fun it was to read a PC magazine in 1990, or go into an Egghead store to see the latest software and hardware?), and while the technical advances have started to leave me behind, I plan on chasing after them for the mental challenge and the potential profit margins.
