Hmm... I agree that the blog's organization fell apart when it went from being just Tom's blog to one with multiple contributors. But I think the organization could be brought back fairly easily if we returned to the way he used to set things up.
Remember that this was a Q & A blog. People would send him their questions about MFA's by e-mail, and he would put each question/issue up as a separate post that contained his answer to it. Others could enter the discussion via the "Comments" section.
What if one of us contributors created a post every Monday titled "Mailbag for the week of August 20" [or whatever Monday it was]. Visitors to the blog could ask their questions in the comments section of that post. Then, throughout that week, contributors would check that week's "Mailbag" and if a contributor found a question/issue that he or she felt sufficiently qualified to address, then a NEW post could be created with it as the title and the contributor's advice in the body of the post. And, as before, other contributors'/visitors' advice could appear as comments.
Would others think this would be a good way to function? What about contributor-devised topics... should we have those going on too, or just answers to visitors' questions? Either way, I think someone should create a mailbag every Monday, so I'm creating one in the next post.
