goodreads vs. librarything

[firecat]

When I posted here that I had joined the librarything cult, someone invited me to join goodreads also and then several people added me there. (I'm 'firecat' on both sites.)

I've been using both of them, but I find goodreads much harder to use (mainly because there's no batch editing feature, which librarything has). If you have used both, can you tell me why you prefer one over the other?
