We've got to hand it to people who spend all their time on Twitter. Most of them (at least the folks we follow) have a real knack for saying something funny or smart using very few words. That 280 character limit might feel oppressive to some essay-writers (try a thread) but we think it forces people to be a tad more intelligent in their writing. These tweets may not be the genius we're referring to, but they're definitely a good way to waste time.
