I know it's as "old as the hills", and so on, but this was the first time I was feeling it too. But I think it's because one satiric comment just got a lot of attention [1], then other people started to do a bit of satire as well. Which is why it feels Reddit like. Looking at the other comments and top child comments, I don't see it either.
