Question(s) in regards to postings on Craig's List...
1) Do agents ever comb Craig's List(s) finding posts of would-be published writers who are wanting an agent?
2) Should would-be published writers give credence to Craig's List posts from literary agents/agencies soliciting manuscripts?
Legit agents usually have their hands full with the slush pile. If they are looking for writers, generally they're looking at actual writing (blogs, short stories online, lit mags etc).
Please do not interpret this as a slam on Craigslist because I am devoted to it for other things-arranging poodle play dates, getting help with computer issues, rants and raves, the free/giveaway section.
