I have to agree with Matt and the team. This is one of the cleanest forums around: easy to search if you have a specific problem, a pleasure to browse if you're just looking for tips or some added info.
Why would want to go talk drivel all day about god knows what on a dedicated WP forum? If you want clutter and nonsense, you should perhaps visit MySpace or something. Seriously though, I think it's good as it is, and any changes should be in functionality, accessibility or design, not content I think.
You could always create your own somewhere. If the need is there, it will certainly become a popular place in no time. What do you think?
Thanks for blogging!
