korra: abuses hashtags and uses way too many exclamation points
mako: essay writer; bitches about the character limit
bolin: can't figure out how to do anything
asami: retweets things like first world problems and other things she finds funny/cute/inspiring; all of her original tweets are song lyrics
tahno: only posts pictures of himself he takes with instagram
amon: links to social justice essays; also feels victimized by the character limit and uses lots of hashtags to spread the word about his movement
lieutenant: livetweets his entire life
tenzin: refuses to get an account; korra makes a fake one and pretends to be him, and she's the only one who thinks it's funny. bolin plays along just to humor her.
