Yeah, they're new sneaky features recently added in.
And it's not just blogs. Images, articles and all other submissions (including media) have view counters as well.
I swear there is one more new feature that I remember seeing recently, but I can't remember... EDIT: Oh yes, a new link called Post History added to the Community section, though the Post History itself is of course not new.
That's pretty neat! I didn't notice them until I saw this status :3
I don't get how the update dates work though. For example, it says I updated ALL the images in ALL of my games today (which, I definitely did not do). As it seems, it's the time stamp of when it was last VIEWED instead of updated.
