Well, not surprisingly the Adobe team went and mucked up what I feel is the best forum on the Internet. They made it look like every other forum on the Internet, with just too much going on.
The clean, plain simple look of the current forums is superior to any other I've ever seen, and changing that is just not worth whatever new 'forum features' might come along. If you can't add new features with the current look, then just don't do anything.
Specifically, the original author of the post is a "who cares" type of thing. It's not needed in a message view. This is worse than what we now have.
Likewise the "views" and "replies" are not required information, and only serve to mess up the view. This is worse.
The message Subject has too little room to display, so it gets wrapped to a second line. This is worse.
Maybe it's not obvious, or not implemented yet, but I see no flags telling me there are replies that I haven't read yet. This is worse.
When you open a message thread, we have the familiar "forum look" which is very much worse than the very clean look we now enjoy.
Like the Home/End shortcuts, and the handling of subclips, Adobe went and 'fixed' something that wasn't broke, thus effectively breaking it.
