spam be-gone

I've been receiving (and deleting) a lot of "comment spam" on my older posts. Comment spam are unrelated comments that list website url's in an attempt to improve search engine rankings. So I have turned on comment moderation for anything older than 30 days. You are still welcome to comment on older posts, you will just have to wait until I get around to approving the comment before it appears. It is rare for me to receive real comments on old posts, so I don't think it is a problem.

Again the rules for comments here:

1) Keep it civil.
2) Don't speak for anyone else or assign motivations to others.
3) No unsupported accusations.

#2 is the rule most frequently violated. I want to hear what you think, and I believe a free exchange of views in a public forum is important to our communities.
