I won't do it for friends unless they actually have a clear brief of what they want. I'll do that, and nothing more, and then tell them they're on their own unless they want to start paying me, because I already gave them free time.
Family I'll do, but only when I have time, and thankfully they understand that.
More thankfully, only two of them have actually asked for anything, and neither were real sites. One was a blog and the other was *shudder* a MySpace layout (stupid slut cousin)... MySpace makes me feel dirty :'(
