Are you procrastinating too much? Where?

Hey fellows!
Which websites do you use to Procrastinate? Twitter trending topics? Youtube related videos? 9gag? Stupid-news-websites (which of them?)?

What other websites? I need to create a list of them, in order to add them in my extension to stop procrastination (StopProc).
We can stop this virus, together! 🦠 (the Procrastination virus)
