I'm primarily a utility/commuter cyclist. My bike is a touring bike equipped as a commuter (drop bars slightly higher than seat, fender, lights, rear rack able to hold 25kg). My next bike will probably be a cyclocross or comfortable road bike (like a Roubaix). I do a few casual fun rides by myself or with small groups now and then. I ride year round and have no car. I'm not a mechanic, but I do the typical amateur maintenance and minor repair many cyclists do. I'm not really an expert in anything except makeshift cargo loading
I've volunteered frequently with my local cycling advocacy group for a few years and this year I'm on the board of that local cycling advocacy group. I'm often encouraging people to cycle and helping them to do so in many ways in my local community.
I've been involved with online/electronic communities since dial-up modem BBS systems in the early 90s. I ran my own BBS for a while back then, and assisted with running one or two other more popular ones. I've been a newsgroup moderator, and mailing list moderator. I helped start and run a linux users group and a system administrators group.
Professionally I used to do more programming but have been doing much more Linux Systems Administration for about the past decade. I think I'd checked out Stack Overflow, but it didn't have much interest for me. When "the trilogy" was announced and ServerFault was created that was much more interesting to me. Early on I was very active there and was on the first page of high rep users, but have since slid down to the third page. When I saw a site for bicycling on Area 51 I came over and checked it out. I don't remember if I was involved in the private beta stage or not. I was very active, got a good amount of reputation points, and was asked if I was willing to be a pro-tem moderator.
Basically, I'm even-tempered, experienced with online communities and specifically experienced with how Stack Exchange sites should work.
For about the past year I've been a pro-tem moderator. I try to be impartial and fair. I usually don't get too emotional about online disagreements, but when I do I usually have the sense to walk away and come back later. If I make a mistake I'm willing to admit it and fix it. If I disagree about what should be on or off topic here, I'm willing to go along with the community consensus. I'm willing to learn to be a better moderator and will continue to try to improve.
I enjoy helping an online community to thrive. I believe my efforts as a pro-tem moderator have helped with that, even if most of the job is fairly invisible. I think we have a good community here, full of people who like to help and to share their knowledge.
Some of us pro-tem moderators have been very pro-active with fixing questions. As the site grows I'd like to see more of the community (high rep users) closing and/or editing questions that need help, etc. Even though I think the long-term goal should be more community "policing", I wouldn't at all mind dealing with more flags. Right now this site averages about 1 flag a day, which is really quite little effort.
