I see that people are posting in the thread instead of wiki so:
1. 'Explore New Features':
a. The first feature bounces around for awhile, then the other features flash by too quickly. Is it possible to display all the features on one page so the eye can glance over them all at our own speed? Perhaps a one or two word description that will give a full description when we hover over it. That way we don't have to waste time waiting to go through the whole menu of changes.
b. After the current menu runs its course of displaying all the new features, it gets stuck on the first one.
2. Faded expired posts: Pictures need not be faded, too hard to see. We still refer back to the posts even after expired and pictures is one way to pick them out quickly.
3. Color change in titles of read posts: Intuition says that a read post would be lighter, not darker, IMO. Because a second color is already being used in expired posts (gray), you may want to use a lighter shade of the unread titles for the read titles.
