The big difference Facebook and, especially, Twitter has made is that it is easier for critics to hear other people’s opinions. Even then, though, you tend to hear similar views to your own; after all, if you follow someone on Twitter it’s because something about them appeals to you. I tweeted about PJ Harvey’s new album the other day. The excited response I got from followers was amazing. But then, what did I expect? I wasn’t talking to fans of Justin Bieber. We don’t really connect.
