I'm going to commit a sin and mention #twitter here on Google+.

If you see an article from +OMG! Ubuntu! tweeted or mentioned over on the twittersphere (even if the tweet isn't by us) you can see a short preview of what it's about by clicking on the tweet. This only works on the website and apps that support Twitter Cards

Props go to +Sam Tran for implementing it on OMG!, and #Twitter for accepting us in to the Cards programme.
