Might this help us fill the need for a place to discuss?
I'm one of those users that would like an area for discussion with the rpg.SE community. But I don't think BlogOverflow is the right tool for that. My understanding of it is that instead of open discussion, there are designated posters who write for the blog. At best, I feel like we'd get an approved topic or two every day to discuss but there would be no way for an individual to ask a question. There might be value in this sort of moderated discussion but I don't think it'll satisfy community debate the same way a forum would.
Blogs aren't really discussion, just people holding forth in alternation, but sure. If someone wanted to walk us through the getting started items in Meta to where we thought it would really be sustainable, we could do it. It would take a lot of commitment, however.
