ksouth, my opinion, the re-design resuted in discussions being less "out there" than they were in the older system. You could see at a quick glance who was posting and what about, easy to keep up with an ongoing discussion (or cat fight, LOL). But the way Forums are set now, someone starts a topic, asks a question, maybe one or two folks respond, if that many, and it dies out pretty quickly. (With the glaring exception of the political rhetoric on Kitchen Sink.)
There is the Q&A section (not QOD), a 'repository' of frequently asked questions from the past, with updated relevant information. Remember "What is the twenty dollar trick?" LOL. I suspect Q&A was created to reduce the repetition of such questions in the Forums, though I don't know how it would prevent that. It is set up to allow us to reply, but few do. And it must not be monitored because I've seen no replies to the few replies!
The QOD section is distinctly awesome, IMO. Outstanding researching and explanations. And they often elicit a lot of discussion from posters. And the way the QODs are archived is great. You can find any topic from the past and all the discussion that ensued. We can go on vacation and still read all the QODs that were done while we are away.
The Polls, they elicit a lot of discussion.
The Blogs elicit some discussion. The Pod Casts...well...
And I really like the News of the Day section. Can't reply to it, though, which is probably a good thing.
