Goodreads looks nice - but is rather unresponsive. There are many similar sites - but I have not yet found any that would make it easy to do the practical things - like finding people who would like to talk about a book (instead of just finding out who has read one), with added bonus if that was also location aware or finding bookclubs with most similar reading taste to mine.
