According to new analysis of tweets sent on Inauguration Day, just 4 percent of tweets sent were negative or "not interested" in events.

The White House shared a "surprise" on Tuesday when first lady Michelle Obama tweeted a warning that she and the president were going to greet a tour at the White House.

Shhhh! Barack, Bo & I are about to surprise folks on @whitehouse tours! I love doing this. Watch here: wh.gov/live –mo

Beyonce was the queen of the inaugural ceremony on Monday, at least when it comes to chatter on Facebook.

Rep. Pete King (R-N.Y.) knows Beyonce when he sees her, but maybe not Jay-Z.

Capitol Hill looks a lot different on Tuesday than it did on Monday, Rep. Bruce Braley (D-Iowa) noted in a tweet.

Where did everyone go? 21 degrees. Wind chill near zero. Back to reality. twitter.com/BruceBraley/st…

Kelly Clarkson, Eva Longoria, first lady Michelle Obama, members of Congress and about a million other Americans were tweeting about inauguration on Monday, when President Obama was officially sworn in for his second term at the Capitol.

Twitter said on Monday that 1.1 million people tweeted messages during President Obama's second inauguration.

The figure easily surpassed the 82,392 tweets sent during the inaugural ceremony four years ago.

Although there was more excitement for Obama's first inauguration, the social media service was still in its infancy in 2009.

Sen. Claire McCaskill (D-Mo.) used her perch on the inaugural platform Monday to dish some sartorial criticism of Supreme Court Justice Antonin Scalia, who set off a social media firestorm with his choice of headwear.

Scalia appeared to be wearing a Tudor bonnet, the traditional academic headwear for those who have a professional doctoral degree. The hats, typically made of velvet or cloth, are customarily a soft round cap with a cord that circles the puggaree of the hat. They are most usually worn during graduation ceremonies.

Scalia's cap did not appear to have a cord, but otherwise resembled the Tudor bonnet. Whatever the style, the hat was "weird" enough to earn liveblogging from Missouri's senior senator.

The percentage of members of Congress using Twitter has more than doubled in the last two years, according to Twitter.
