So, after the bright minds of the marketing world have been predicting the death of email for years now, all of a sudden Twitter is inboxing you with notifications on anything that is sent into the Twittersphere with your Twitter handle in it.

But now this screenshot from an earlier build of the feature leaked, which shows why the feature actually was launched. And all of a sudden, it all makes sense.
