6 January: The great Twitter outage of 2015. For a few hours, people couldn't see anyone else's tweets, but they could still post them.
So everyone did the sane thing and shouted into the abyss about how horrible it was.
It even forced some people to use other websites. The horror.
But eventually people realised there was probably a reason for all of it and went back to tweeting as normal.
Well, except a few. For some tweeters, it was just too much.
