@AndrewJ, a button that toggles between listing posts chronologically and by thread would address that, I think.
@JordanHarris, one possibility would be simply to use Stack Overflow -- I'm sure there is some way to trigger an alert whenever someone post a question with the JUCE tag. Better than reinventing the wheel I think!
It would also be nice to be able to work in an RSS feed (if that's the right term, I've never used it until today) so that subscribers can be notified whenever there is a new post.
That's what I've just done today on the IRC channel bot -- whenever a new commit is made to the JUCE-master repo, a notification appears on channel (which is logged btw, log URL in topic).
It would be funky if any forum post or SO post also triggered a notification.
That would mean only one place to look to keep track of JUCE activity.
