Let your readers copy edit your content., originally uploaded by Stowe Boyd.
For some reason I find the idea of having blog readers helping out with copy editing a bit odd. First off, you are a blogger, so presumably you have some calling towards writing, story telling, criticism, whatever. Presumably, you have a grammatical brain in your head, and after all, when you hit the post button, you theoretically have proofed what you have written.
However, there is a variant of this product that might make sense: imagine giving access to a small circle of friends to review something you have written before publishing it. Like a preview blog that is password protected, so you can get some feedback — and maybe copy editing advice — before going public with it. That I might actually use. But this version of GooseGrade I can’t wrap my head around.
