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 less.

The week's best new users: Say hello to Mark Boal, writer of Zero Dark Thirty and The Hurt Locker, and football legend Joe Montana. Also, Digg Kickers is a feed of every story on Digg, but with the excellent subheadings instead of headlines. It's all kinds of great.

Photo of the week: Here's an island (the Chatham Islands, east of New Zealand) that looks like a the Ghostface character from Scream when viewed from space. (@Cmdr_Hadfield)
