Goodreads is an excellent, mature, website with a vibrant community. I use it all the time and have never noticed it lagging or had trouble using a feature. I think it looks and works better than most of the space-wasting, feature-hiding, animated sites online today. I review a few books a month on there and end up in interesting discussions frequently. The amazon kindle integration, with ability to publish your notes on a book, is a killer feature for me. IIRC they had this before Amazon bought it, too. People seem to dislike the recommendation engine. I can't comment on this because I didn't notice it even had one... it's not a feature I'm looking for. I guess I get that from friends and possibly from the main Amazon website.
