Well, figured I should chime in since everyone mumbled my name when Michael said "quantity not quality..."
Here is my theory (or rationalization?). I for one have a ton of stars and posts but am in no way a hard-hitter as far as mechanical ability. In fact that is one reasons why I am so prolific -- I end up asking the same question twice
Other factors include:
1. I have been here pretty much since the beginning and unlike some who come and go -- I never leave. My lifestyle is such that I am near a computer all the time. At home, its right there in the center of our living space -- and at work its my primary tool. Always connected to the web. So checking in is never very far away.
2. I only work part-time so I spend a ton of my free time obsessing over my car. I know I am blessed to have such a toy and I enjoy messing with it. And it is a bona fide driver and life-long project. So before long, questions come up and I know who I can turn to.
3. I enjoy the company. I know we all share a passion for these cars, and its fun to see others as into them as I am. Moreover, the connections on the site have led to friendships and to some fantastic gatherings over the years. So when I see an opening in a discussion, I jump in to try and continue the comraderie. And, finally, having owned my car for over 20 years, I think once in awhile I add something in the way of experience...
