My biggest pet peeve is a story summary that has spelling errors. I don't know why, but if I see one for a story, I end up skipping it all together. Despite this, my own writing habits are terrible. I write, reread, edit, and post. That's about it, not more than that usually, which is why I'm always updating and changing stuff if I notice it later on... Like I said, terrible habit. I write in spurts and go through lots of dry spells. Sometimes a year at a time.

I love reviews, they kill or feed the ego, a healthy balance of course.
