I suppose this question has been asked before, but please humor me, since I'm new. Does anyone use them? Have you found them useful? Are there any particular ones you've found helpful? I've been browsing through a few, and they seem interesting. Some are pretty far out there. (The girth of my character's tail? Really? I would be seriously worried about her if she had one.) I can see where they might be useful though. They give me food for thought. They present me with ideas about my character that I haven't considered. I suppose they could give my character more depth, which I'm sure is a good thing. I'd just been happily writing along, not thinking that she needed to be more of a person, with more feelings and history. Does it really matter what her greatest fear is? What she was doing between the ages of one and three? Maybe so, maybe not. I guess it depends on the story, hmm? What are your thoughts?
