I hadn't really heard about keybase yet, but does it solve the only problem worth solving in encryption? Does it allow me to take any email address and give me back a private key that only the recipient can use?

If I wanted to know which public key to use I would just look at the recipients public website or ask that person through a phone.

The problem is that people don't create keys because nobody ever send them anything encrypted and people don't send anything encrypted because nobody ever sends anything encrypted.

But if keybase is just another storage for keys, what is the point? Especially if it is going to add a pointless waiting list that is just going to make the problem of not having a key even worse.
