I've found this really works for me. Unless I'm wordwarring, when I write, edit, or read anything, I log out of twitter and email. There's this sense that we're missing out if we don't have such things on all the time, but for me personally, you can catch up on virtually anything after the fact if it's important enough. Like the fact you filled Adam/Godstiel, omc, I didn't know, but I can read now through lunch. See? The theory works! :D
