There is no writer on this planet that cannot be significantly improved with an editor, if only to take that step away from the self necessary to view the prose clearly. When writing, everything gets filtered through one's own perceptions; one's imagination makes up for lack of clarity in the prose, and only a second party can really find any gaps that occur. Despite what you hear, writers are not, nor should they be, writing for themselves. Writing for yourself is what you do in a journal--and not even an online journal, but an honest paper journal shoved to the back of the sock drawer, something that nobody will ever see but yourself. When you're writing with the intent of publication, you cannot afford to be self-absorbed. The story is--or should be--much bigger than its author.
