With hundreds of millions of tweets per day, it’s impossible to follow everything happening on Twitter. Every Friday, the Daily Dot rounds up notable Twitter news and stories from the past week—in 140 characters or fewer.

  • Your favorite Twitter apps have just a few weeks to change how they hook into Twitter's data. Here's what'll happen if they don't.
     
  • In shocking news, Twitter CEO Dick Costolo wants a billion people tweeting. He also admitted it can take a while to really “get” Twitter.
     
  • Manti Te’o, the football prospect with the not-so-real dead girlfriend, quit Twitter. A smart move, unless he's starting some fake accounts.
