This morning, connecting to twitter, I saw a new infor;ation on top of the window : twitter added to my account as beta group member the new "Retweet" functions.
It looks good, and give added value : instead of the classical "RT xxx", my followers will see the initial tweet with a small mention that show I've re-tweeted it.
It will be more "readable" for followers, especially in case of multiple re-tweets
We will not face anymore the "more than 140 characters" issues when re-tweeting !
The small inconvenient I see is that using this, I cannot add a comment (to explain why I re-tweeted). But maybe it's not so important !
