Folks at Twitter have gone and searched all the tweets of 2010 so far, 25 billion of them, to find out the ten most powerful tweets. Of course announced via a tweet.
These tweets extended from a reporter / journalist Ann Curry facilitating a landing of a plane full of Doctors without boarders in Haiti, after the 7.0 earthquake to lame Conan O'Brian road tour announcement.
It also had gems like (a real powerful tweet) FIFA World Cup Final which also used telepresence in a big way;
I also like the tweet by Whitehouse welcoming Russian President to the Twitter
All in all, it was a good twitter year.
See all ten tweets here.
