Editors and agents don’t care if your material has been posted in online critique forums. In fact, some publishers are actively searching for unknowns online, as evidenced with publisher-founded writing communities such as Authonomy (HarperCollins) and the brand new Book Country (Penguin; see today’s Publishers Weekly). But don’t post in online critique communities with the goal of being “discovered.” No one can attest to the odds of that happening or even to the likelihood that publishing companies can realistically maintain such a communal ideal. Post because you seriously want critiques and you seriously intend to give them. Because when all is said and done, the reason such forums exist is to serve your very real need for constructive, objective input on your writing. Before you commit to any critique community, follow it for a bit to get a feel for the quality of participants’ criticism. Then work to build relationships within that community that are built on respect, dependability, and trust.
