I try to make a clear delineation when I beta. Some people just want grammar and spelling and...usage for lack of a better word. And then, some really want a cheerleader and I can do that, but I have to *know* you want that. And I do try and match up with someone who has a similar style. I'm not great with huge descriptive passages.

I had a beta, earlier in the year, who I just didn't mesh with at all because she thought I was 'leaving out' huge chunks of story and it was really that I just hadn't gotten there yet. She wasn't a bad beta, she just wanted me to tell the story in her way and...I didn't.

And yeah, there's always that fear of breaking another writer. But we all have that terrifying feeling just before we open the edit, that it was awful and can't be fixed. So, I think most of us guard against that.
