#Hindsight2010 @twitterhttp://snapvoip.blogspot.com/

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;

The FIFA World Cup final represented the largest period of sustained activity for an event in Twitter’s history: during the final game, people from 172 countries tweeted in 27 different languages. Twitter put fans in direct touch with teams, players and commentators--and when Spain celebrated its big win in the Final, defender Carles Puyol captured the zeal with a Twitpic of the scene from his perch at the victory ceremony.

I also like the tweet by Whitehouse welcoming Russian President to the Twitter
All in all, it was a good twitter year.
