Nice idea, but why depend on dialog at all? Surely the Git Way™ would be to accept switches or subcommands to pick which stats you want to see, perhaps with an optional interactive mode.
Additionally, judging by the name this is meant as a Git custom command. It should therefore be possible to run it with `git quick-stats`, like any other Git command. I'd suggest updating the docs to confirm that this usage is possible and recommended.
Well, yes, Keybase.io acts as a centralised location to find all the identity proofs, but you don't actually need to rely on it - the proofs on each external site can be independently verified without any help from Keybase.io.
