Vladimir Putin has ruled Russia for twenty years, but he has a problem: his current presidential term ends in 2024, and the constitution prevents him from running for re-election then.

Something that Kayvon Beykpour, head of product at Twitter and I talked about, and the thought was: Twitter doesn't give you a lot of disincentives to be a jerk online. But what if there were a way to measure how much of a jerk someone is and put it right in their profile? Wouldn't that help? I think it's a pretty good idea. Though, you can see the arguments against it.
