Social reading in the sense of the Goodreads thing is fine, though it's not something that I use at all. However stuff like the Amazon tweet/fb when you've finished a book irritates me immensely, and also the fact that when you're in a book on the PW and bring up the Menu, the @#$%* Share button is there too. Luckily none of my friends use that stuff either
We talk books when we see each other...
