The top tweets of 2011 were about breaking news, impromptu meet-ups

Twitter co-founder Jack Dorsey revealed the top 10 tweets of 2011 to ABC News' Diane Sawyer on Thursday. And unlike the most-shared articles on Facebook, the year's top tweets were largely breaking news-driven--and not dominated by human interest stories involving children, parents and/or dogs.

Tweets about the revolution in Egypt, the earthquake in Japan, riots in London and raid on Osama bin Laden's compound were among those that made Dorsey's handpicked list.

For example:

2. "Helicopter hovering above Abbottabad at 1AM (is a rare event)." A local man in Abbottabad, Pakistan unknowingly live-tweeted the raid on Osama bin Laden's compound before any news agency broke the story of the terrorist's death on May 1.

Other top tweets involved impromptu meet-ups--like this one:

4. "This lockout is really boring..anybody playing flag football in Okc..I need to run around or something!" "Twitter makes the world feel a lot smaller," said Dorsey. That was definitely the case during the 2011 NBA lockout, when Oklahoma City Thunder player Kevin Durant tweeted, "This lockout is boring…anybody playing flag football in Okc…I need to run around or something!" A student at Oklahoma State saw the tweet and invited Durant to join him and his fraternity brothers in a game. A few hours later, Durant arrived, ready to play football with them at a local field.

Interestingly, with the exception of a pair of Twitpics, none of the top 10 tweets picked by Dorsey included links to content.
