So post counts, message counts, rep points, and all those previous details are a thing of the past now? I know you can see them when you actually click on a profile, but I did like seeing that info under user avatars for quick reference.
Definitely not a thing of the past, but in an effort to speed page load (largely due to mobile), they are now available by simply hovering over the member's avatar. It is really nice because you get much more information about the user by hovering over their avatar than you could have ever gotten in the past but at the same time, it doesn't crowd up the posts.
