And yeah, I think The SF Author LJ Contingent (and other blogs that are similarly slice-of-life) goes a long way toward somewhat scrubbing away those false images. Because you blog about your actual selves, you know? About making pear butter, and bringing home a new dog, and Car Trouble, etc, etc.
Because you guys are Writers, you can make these things sound exceptionally interesting, while at the same time filling out that picture in our heads. You become less of a blank slate for us to project our Crap onto, and more a person who creates awesome for a living.
