I have known about Wikipedia for years. I've used it frequently over the past couple of years, especially when looking for information from my BlackBerry.
I first heard about the concept of a wiki about ten years ago, and wasn't impressed at the time. I went to work for a new company in September 2006 and they established an internal wiki soon after. That was my first exposure to editing a wiki.
I created an account here in order to post a comment on Xylitol without showing my work IP address on 2-Oct-6. I started making minor edits that afternoon.
I can see where I could become a Wikipedia:WikiGnome or even a Wikipedia:Wikipediholic (score is from 14-Oct-6, and doesn't count the 1000 points for realizing you were close to the end - I felt that quadrupaling my score was a little extreme).
Steve Young (NASCAR) - There is a auto racer named Steve Young, but he hasn't made it up to ARCA yet, much less NASCAR. The NASCAR site only goes back to 1975, so it isn't clear if there was a historic Steve Young who participated prior to 1975.
