Hover Over Profile

I think it would be beneficial to have hover cards. This means if you put your mouse over a user's name a card pops up about their profile. Take a look at the imagine below.

Their amount of posts, rating, name, about them, etc. I don't want to navigate away all the time.

Also, it would be cool instead of seeing "Recent Posts", just to display categories.

"Select a category, and a drop down menu will appear with the most recent posts in that category."
