And I wanted to express my delight with stackoverflow.com, which has proven its worth and demonstrates it readily. I'm also delighted with the promise of hunch.com. It takes a little diving into at this early stage to really understand it, but it's apparent that it's an experiment worth trying. (This is how wikipedia felt way back when. I wasn't sure it'd really work, but I was glad somebody was giving it an honest effort.)
Yay for people helping people.
