I don't see meme overload - was a change made?

No, they just burned themselves out posting a bunch of memes several days in a row. They didn't really go anywhere and it'll come back. Don't fret, however, because a "subscription" feature was being worked on so you can choose what boards you want to see (and what you don't). No idea when it'll happen though, because I heard about it 4 months ago...
