Scribophile is a place where you can read things others have written, critique it, and then post things you've written and get feedback. It's quick. It's easy. It's fun.
If you're not quite ready for eye contact with those that critique your work, I think this online group might be just what you're looking for. It could become a time waster, but at the same time it offers a yard stick to help you gauge how a specific story or scene is progressing in the eyes of others.
