Twitter is exactly what you want it to be. You curate it. You choose who to follow. You choose what you see. You choose what you learn. And it can be a little clunky getting there, I won’t lie. But it can also be fun and wondrous: finding some new source of information that tickles you, and diving down their rabbit hole (who they follow, for a start) to find even more people with deep knowledge about a subject you may have felt very few people cared about in the way you do. You never have to see anything you don’t want to. (In settings, you can choose to have Twitter make suggestions. Choose not to.) Some people rush to what’s trending. I don’t usually care. (But occasionally, I actually do, and that’s fun, too.) Twitter is crammed full of total idiots. That’s true. But it’s also a place where a whole lot of the best minds on earth congregate to broaden their knowledge, try out ideas, and share what they know best.
