My problem with Goodreads is actually the site performance. It's one of the most abysmally slow sites I've ever had the displeasure of using. Loading from page to page takes so long, I wonder if they're running on 486 machines in the background. It's unfathomable to me how something that has such a monopoly on the domain can have such terrible performance.
It's so bad, that I often don't even bother going to Goodreads except when my TBR pile empties out, and then I spend as little time as I can (which is a long time because it's OH MY GOD SO SLOW) so I won't have to visit it again for a while.
I wish it was open source, or something, so I could contribute to improve response times...
