It's been interesting to watch who comes on with a flurry, posts daily for months, and then just disappears. EjustE comes to mind. He Joined September 22, 2009, made 3673 posts in 11 months exactly, his last post was on August 22, 2009. (see http://www.bikeforums.net/memberlist.php)

EastHill was another great contributor. She left for good reasons, which she confided in me. She and I used to post in the 50+ but both quit at the same time because it got so snarly, and not in a SnarkyPup sort of way.

I've only been a part of it for about 5.5 years at this time. Time does fly.
