Add sorting of posts by Updated

While it's something in the right direction, that statistic seems to be updated on delay. My first comment from yesterday only appeared today and my today's comments are yet to be included. That '1 day' delay is a bit of a problem when you want know 'what's happening now'.

Also, it doesn't show any context for the data. What was  the comment? What post did it comment on? How many replies does it have? Etc.

As a user this is not useful at all, sorry.

All I care about is seeing active, relevant content and other people seeing mine.

If I reply to a post from 3 weeks ago, unless someone is subscribed to that post or specifically searches for it nobody will ever see my reply.  This is a problem.

Edit: If the main goal here is a question & answer site and not a forum, then ignore everything I just said.  But so far, this is definitely giving more of a forum/discussion vibe.  Personally, I think they should be separate.  Paul mentioned having "Questions" and "Articles".  How about a third type; "discussion"?  Each type/category should and could have its own default sort behavior.

I think this might be the problem, or the source of my confusion/misunderstanding in the other topic.  I did a quick example in Excel.  As you can see, the post with the most recent comment is still at the bottom.  I think the expectation of most users is that the posts with the most recent activity would be at the top of the list.

Feel free to correct me if I'm missing something.

If the breadcrumbs don't come back in this release I might ragequit!  :)
