They're great but really, really not the whole story. Not by a long shot.
(except for microfiction, of course)
Words > sentences > paragraphs = story
I like stories too, but feel it's more important to hone the first three before considering them as a competent whole. If you can nail the first three, then an editor/publisher is more likely to continue reading and eventually find out whether you've written a bad story, good story or excellent story. If you don't nail the first three, chances are, even if you've written the greatest story ever written, the editor/publisher will likely never find out.
That's my thinking and why I'm taking a year to well and truly hone all three before committing to what I would consider a marketable story.
