For me I look for bold forum title or thread names.The update seems to work well for me, but I do miss the little blue dots when there are posts to a thread that I haven't read. Is there some way to know if there are unread posts?
As a matter of personal preference, I don't care for it, it takes more steps to log in, more steps to log out and the security issue requiring hit back and refresh page does nothing to endear me to it, nor does the failure to complete loading pics.
I will continue to visit and peruse the subject matter, no real issues there, just to me, nothing is notably better.
