Last night, President Obama gave the 2012 State of the Union address, and Twitter users immediately took to the platform to livetweet their #SOTU reactions. Over at the Washington Post, Eric Wemple provides some interesting reasoning as to why Twitter is the perfect tool to complement live TV. His main argument is that Twitter is ideal for capturing the minutia–reaction shots, jokey asides–without interrupting the overall flow of the event. Twitter users seem to agree, considering the sheer amount of people tweeting about the event last night.

Twitter has put together an infographic to illustrate last night’s activity on the site, including this whopping number: 766,681 users tweeted between 9:05pm and 10:40pm with a State of the Union-related hashtag. Congress jumped in on the action, too: there were 548 total tweets from congressional members during the speech.
