I've had a few run-ins with some self-appointed critics who gave the impression that they knew everything because they spoke to a publisher or editor who told them it was acceptable to use poor grammar and pass it off as "Hey, why be bound by rules?" Meh...
Goodreads is, IMO, good for what it is, but as with any forum, there are cliques and cadres and a whole lotta butthurt at times. So I just list my books, do reviews for those I know (or books I've read in the past before joining up with GR), join in a few conversations, put my book up for review, and let it go at that. There's no point in arguing with someone there. And yes, I always thank my critics whether I agree with their rating or not.
