I like the green-dot system very much. It definitely helps people new to CD feel more comfortable posting. It's a little nudge; a way-to-go-chap-your-post-adds-flavor-to-the-mix. It's nice to get feedback that your thoughts can be insightful.
The negative rep points have their pros and cons. One of the bigger pros I see is that it lets the people of CD inform others when they might be a tad out of line, and should maybe reconsider their actions. However, a PM could do the job just as well, I suppose. The red dots should definitely be used sparingly, as I believe they are.
Anywho. From a [relatively] new user...all you Chief Delphi-ans: Keep on, Keepin' On!!
