Google+ for Android has been updated today to include to a few fixes plus a very important feature. It is the ability to display richer snippets from the things that you posted.
As you can see from the above picture, if you post a link, it will display in a richer format. I think this will be more interesting than just a link. Here are the changes in this version 18.104.22.1689322:-
- Support for hashtags in the stream
- Improved sharing support for 3rd Party apps
- Bug fixes and performance improvements
