Record screencasts and share them on Twitter with Screenjelly
Screenjelly fills the gap between screenshots and full-on scheduled videoconferences. If you're having a computer problem, or fixing one for a friend, sometimes a screenshot can't fully explain the unusual behavior you're trying to deal with. A short video can do the trick. Similarly, if you want to show off a cool move in game you're playing - and there are TONS of videos like this under three minutes on YouTube - you can have it blasted out to Twitter within moments of recording it.
