The likes in my opinion feel like they're trying too hard too hard. It just reminds me of that Office(US) episode where Ryan was making the new Dunder Mifflin website this new form of social networking or something. It feels really childish too. Is it enough to make me leave? No, but that doesn't mean that it isn't annoying. I can stand the likes, and that bullshit, but I really hate the backwards reply.
