they are watching beautiful animated gif google+ and truth that are very good for condividir and make our most interesting posts.
I have not seen that with twitter and facebook you can do the same. It is one thing to do only posts by google+. Upload a photo in animated gif format and view it directly.
Those who have not yet proven it would be a good idea. Try to post an animated gif in facebook, in twitter and also on google+ and you will see the difference.
Below I show some of the more good I've seen on the internet.
