Honour your failures, and celebrate!
It’s the Fail Whale, the image that is displayed whenever Twitter is “over capacity”. Every Twitter user is familiar with the Fail Whale.
Of course, it’s not the Fail Whale itself. But the whale is a symbol here, it stands for Twitter’s open, relaxed, ironic and fun way of handling their problems. “Look, we sometimes screw up, but we’ll try to make it fun for you,” they seem to think.
And it works!
