A good article that covers what Keybase is, where they came from, what they try to do, and where they're trying to go -- although you couldn't tell from the headline. As in the article body, Slack is namedropped just for effect; Keybase Teams being a decent proof-of-concept of a popular kind of application to show that the ideas behind Keybase can be used to build real products.<p>That being said, Keybase has been moving more and more towards building these higher-level services on top of (and app-wise, deeply integrated into) their core offering: Chat, File locker, etc; presumably other than delivering value these offerings make the company easier to position in the grand graph of services, and more palatable for raising capital or as a future acquisition target.
