I think it's a good move that they are making +1's shareable. At first I thought I wouldn't want to be spammed by +1's, but if they aren't shared, then there isn't much point to them anyway, is there? And it might not be so bad. But are they going to make +1-ing a 2-click action, instead of one? I'm not sure what to think about that yet.
