Where Miss Snark vented her wrath on the hapless world of writers and crushed them to sand beneath her T.Rexual heels of stiletto snark. The blog is dark--no further updates after 5/20/2007.
Who: Miss Snark is/was a snarky anonymous agent who loved both George Clooney and poodles. Her sense of wit is second to none.
What: As an agent, Miss Snark was uniquely placed to offer 'insider' tidbits to hapless writers - and she did. I have an impression that she was one of the very first agents to begin blogging; she was certainly the first to call for submissions to her 'Crap-o-meter', where she offered critiques of people's query letters :) This site is incredible. Her sense of - er, humour - will have you snorting outloud, while the information her site houses is a must-read, must-know for anyone wishing to enter into the scary world of publishing.
Where: Here, or here: http://misssnark.blogspot.com/
Why: Because this blog is a veritable goldmine of information concerning the publishing industry. If there's something you're not sure about, I can almost guarantee that Miss Snark has answered a similar query at some time or another.
When: As mentioned in the tag line, this blog is now 'dark', meaning there will be no more posts. However, I still highly recommend it since it is an unparalleled source of information :)
