IPFS alone is usable for the public web, but is not usable for private sharing. You need a social identity-oriented public key infrastructure with a good UI. That is Keybase, and it's incredible that we have this now. Sure, we should implement an IPFS backend for the storage part. But let's not neglect the huge progress the Keybase folks have given us.

Well, what I'm hoping for from Keybase is enough user friendly tooling to encourage a lot of people to start using public-key cryptography. I don't see IPFS as really addressing any of that, even though it is extremely cool and valuable in other ways.

I love the ideas behind IPFS, but it isn't even trying to solve the same problems as KeyBase, so comparing them like this is very silly. Users may be able to benefit from both in different ways, or even use parts of the two together in the future.
