Google+ has added a few new features in the last week. The first is that you can now share information from your Google Books account to Google+. In theory you can include the books in your Google Books account into posts for Google+. So far, I've only seen the "+1" button (which is partly like the "Like" button in Facebook and partly a way of saying "me too"). It's a strangely incomplete integration.
Google+ has also now introduced games. I am not a fan of games on Facebook, so I think this is a bit of a shame. On the other hand, I had to look for the Games section which means it's not being forced into the main stream of posts. That's excellent. I'm a little surprised that the first round of games didn't include something similar to Words with Friends. That game is social by design unlike Angry Birds or Bejeweled.
