There's a lot of shouting on the Internet. Sometimes it's a heated political debate. Sometimes it's a nerdy discourse on the lore of Babylon 5.
And sometimes it's Nana sending you an email in all caps "BECAUSE I CAN SEE THE LETTERS BETTER THIS WAY." Bless her heart.
In the plain text world of SMS and Twitter, capital letters have become a de facto volume dial. But it wasn't always this way. The folks at Knock Twice reviewed the history of the computer keyboard and charted some of the most-shouted words on the web today.
The Twitter data comes courtesy of the @CapsCop, who collected more than 1 million random tweets over two years to find some of the most caps-locked words and phrases.
