Guess what? I never visit Kotaku. I don't care about 99,8% of that websites output. But you know what? It is REALLY easy to avoid. So people saying "Yay, this website I never went to, that had no impact on my life and that I only see when I choose to might go away and a bunch of people will loose their job, hooray" is simply awful.
You don't have to be sad about that, you don't have to feel empathy for the people working there, you don't have to care at all about this. But the moment you choose to celebrate it, I will call you an asshole.
Edit: I should mention that I'm only talking about Kotaku here, not Gawker as a whole.
