I'm always looking for new places to gather information. Other than webmaster-talk, are there any other recommended forums of use to professional bloggers? Thanks in advance.

I can recommend Aaron Wall's SEOBook.com forum ($100/month though). I couldn't maintain the expense very long, and it's not a blog-only resource, but it was great. Lots of moderators and lots of activity. Every time I posed a question it received a response.

There's many niches out there that are dedicated to bloggers, and many forums have professional bloggers as a few of their regular members.

But for just bloggers in general, you could always try a search:

I also believe Steven (vangogh) is a member of a top business forum, but I can't be 100% sure on which one, or if my assumption is anywhere near accurate. You'd have to ask him about it.

Hmm.. Blogging for forums? I never try it before...
Hmm.. Maybe you can try to blog about the different thread on your business forums, its subtopics, some HOT threads (if there are!).
