I've been a subscriber to LED Digest, a moderated discussion list since, well maybe 5-6 years ago. The list talks about many different subjects related to web sites and Internet topics. They have about 40,000 subscribers.

I'm posting about the list because they have been having some discussions about domain names, but they often talk about marketing techniques, SEO, linking, page editing, and just about everything else.

What makes the list really valuable is that any one can post or discuss things, but the moderator does a really good job to keep it professional and interesting. You will learn a lot if you spend a little time with this list.
