Michael of Half Sigma adds more detail to the nature of his various blog hoaxes, including Libertarian Girl. This is what I found most interesting:

Meanwhile, I started my next hoax project, Abigail’s Magic Garden. The beautiful thing here was that Abigail was a liberal/left-wing blogger! I figured that no one would connect the two blogs because Libertarian Girl was right-wing.

How did I manage to create the illusion of being left-wing? At first I thought I would have to write a lot of stupid stuff that I didn’t agree with, but I made a truly amazing discovery. I could actually write about stuff that I agreed with and still create the illusion that I was a left winger!

Here are the secrets to convincingly being left-wing: (1) fill up your blogroll with left-wing blogs; (2) always mention how you hate George Bush and how he's doing a lousy job; (3) always bring up Iraq when something goes wrong there.

This doesn't surprise me too much, as a libertarian Michael did have intersections with liberals, and so as long as he addressed commonalities people would just fill in the dots for everything else. It reminds me of an article in The American Conservative which points the extent to which coalitional/tribal considerations obviate the need for genuine agreemant in reference to Christopher Hitchens' recent alliance with the neoconservatives and shift toward the Right, he still remains virulently anti-religion and a Trotskyphile, and yet right-wingers like theoconservative Ramesh Ponnuru tend to give him slack!
