Sure you do, the mock-ups looked like this:
Well, Twitter just announced the following:
We’ve just activated a feature called retweet on a very small percentage of accounts in order to see how it works in the wild. Retweet is a button that makes forwarding a particularly interesting tweet to all your followers very easy. In turn, we hope interesting, newsworthy, or even just plain funny information will spread quickly through the network making its way efficiently to the people who want or need to know.
So keep your eyes peeled, because you might be one of the lucky ones!
PS. If you’re not seeing the retweet option, Twitter has a consolation prize for you. It’s cleaning up the spam in trending topics.
