"All while integrating certain Stellar features directly into Keybase's apps."

The rest of their announcement, I legit don't care about. This is the deal-breaker here. You don't need a Big Announcement or to hire more people to add a Stellar address for verification. I know a bit about Stellar as well (granted, you probably know more) but this reads to me as a let's-be-a-wallet game.

And this is worse than having Bitcoin addresses: active functionality versus passive functionality. Difference of kind, yeah?
