If possible, I think it would be good to provide an alternate view of the blogs. An alternate view that was grouped by author, and sorted by most recent article / latest comment would be perfect.
I know we have the ability to select a certain author, and view their blog (from the front page, etc.), but there's no way to know from that view when or if the blog was last updated (or has any entries). I would just like to see a sorted front end list on that function.
So I would go into a sub-forum (or alternate view) called "Blog by Author". It would be a list of blog authors, sorted by who had published most recently or had a comment most recently. There could be some additional info about who made the last post on that blog, and when they posted, etc.
imo, it would make it feel more like a group of blogs, and less like a forum full of random topics.
It might also help to keep old blog entries alive if they are still interesting.
Anyway, it's just a thought. It's already an awesome service that you guys have provided.
