I’ve always kept track of the books I read. Goodreads allows me to do it automatically. I don’t really use it except to find out about books, read reviews, and keep a list of books I’ve read. It never feels like a race or achievement to me, just a list. I do set the challenge each year; but I set it at the rate at which I read, not in order to challenge myself to read more than normal. I don’t find the interface hard to use though, either; I find it very intuitive. I’m very word oriented so it works for me. I don’t use the community aspect of goodreads at all unless you count reading reviews.
