If you’re trying to get published, remember that anything you put on the internet may be used against you in the court of public opinion. Heck, that’s good advice even if you’re not trying to get published.
A survey of agents, editors, and art directors finds that not only do most of them look up potential clients online, but a large majority of them have rejected someone because of what they found (!). Okay, it’s admittedly a small sample, but very informative.
(Thanks to Debbie Ridpath Ohi for the survey, and Richard Sutton for the tip.)
