Election night drove Twitter usage to new highs. The service reported 327,452 tweets per minute as the networks began to predict an Obama victory.

Notably, the president also tweeted a victory message (“Four more years”) before he took the stage to make his acceptance speech. It is, according to All Twitter, the most retweeted post in the microblogging service’s history.

World leaders, including David Cameron and Julia Gillard, also tweeted their congratulations to Mr. Obama.

In 2008, Twitter had no such dramatic victories to boast. On November 5, 2008, Biz Stone announced tweets the night before had posted at twice the rate of the previous Tuesday. And, there was “no whale in sight.” The error whale was a recurring problem for the site in 2008.
