What are the pros and cons of a discussion forum main page
that works like so:
At the top of the page there's a list of forums and sub forums.
Below the list of forums, there's a list of forum threads. It lists the most recent threads from all selected forums, i.e. each forum which has its checkbox checked — see image below.
Initially, all checkboxes are selected. So by default the page lists the most recent threads for all forums and sub forums.
Here's a mockup:

Personally, I think:
Pros:
You can view the most recent discussions for any combination of forums, without having to visit each individual forum.
If [which forums are selected] can be specified in the URL (e.g. in the hash fragment), then people can link to their own favorite selection of forums. And then, in a single page view, find the most recent threads that are of interest to them.
Cons:
A new interface that people have to learn.
Somewhat more work to make this work well with SEO.
What other pros and cons are there?
((And would you prefer this forum front page, over traditional front pages where you click and navigate to the sub forums of interest to you?))
