I'm Bob Strand, and I have been a happy user of Wikipedia since the "early years." I find Wikipedia a really good source for introductory information on topics I know nothing about (but probably should). This is especially true for technical, geographical and historical items.
I've also found many articles that I'd like to dress up, correct, or add information. Every so often I'm able to get the time to do that. Other times, it's that I find a blatant error needing to be corrected....
