At least one author of the "Best Congressional Tweets of the Week" (as picked last Sunday by The Washingtonian) isn't actually a real Member of Congress. So if you are one of the 645 people who have been following the account of @deanheller, thinking that you were communing with the Republican congressman from Nevada's second district, think again.

In fact, until Monday, you've been following "Anon Guy," a Nevada blogger who decided earlier this week to come clean (sort of, since we don't yet know who s/he is), and admit that he or she had been successfully impersonating his representative, Congressman Dean Heller, on Twitter for the last five months. That's the story Anon Guy tells in a highly entertaining series of blog posts that describe how he started the account on a lark last December 28, how being picked up by the aggregator Tweet Congress led to a healthy jump in followers, including "an entire civics class from a Nebraska continuation high school," activist conservatives jumping on the Twitter bandwagon, and a smattering of fellow Congressmen, and how the local media started to report on "@deanheller" and his supposed presence on Twitter.
