Twerrific Twitterers

I haven't quite figured out how Twitter is useful for most writers, but there are two people I enjoy following on this... social network? ... whatever it is:

• Ron Charles of the Washington Post for great news and reviews on books, publishing, writers, and all things literary (and not so literary) .
• Andy Borowtiz of the Borowitz Report for when I need a laugh. (Thanks to Sheila O'Brien for the tip!)
