On a less controversial side of things, I like that I haven't seen full-on spam threads on CD for a while. Please, let us not go back
there...
IMO, compared to much of the Internet as a whole, CD can be a rather more civil place than most. I'm reminded a bit by a quote (that I think might be from Woodie Flowers, and I'm paraphrasing) is that one of the biggest problems in life are those things that we know, that just aren't so. Be willing to take criticism, know when you're wrong, and give criticism where it is due (without jumping into a pot of boiling anger).
As long as CD remains a civil discourse, a resource for sharing, thanking, and working through problems, things will be okay.
