Seems like a lot of people are saying the airdrop and integrating Stellar to Keybase was a bad idea, but I don't think so. There's a lot I like in the Stellar-Keybase integration.
Keeping cryptocurrency keys secure has always been a challenge. Keep them too well, lose your money; keep them not well enough, someone can steal your money. It's a thin line to walk.
Keybase wants to make encryption user-friendly, and keeping cryptocurrency keys secure fits very well to that purpose. This is probably the least painful way I've kept crypto private keys.
Besides, the wallet is pretty functional, and is integrated to an app that's already sync'd to my phone and computer. It's without fuss and just works. Compare that to yet another app which I don't know, need to evaluate, don't trust to keep my secrets, or won't share them across my devices. Here, it's painless.
I personally knew Stellar already, but as a technical user (which I feel is a natural demographic for any crypto to start to get early adopters), this brought back Stellar in my mind and renewed my interest (or would've interested me if I hadn't known it).
Besides, I quite like Stellar as a cryptocurrency for payments: fees are low, and confirmations are near instant. And I'm not even naming the fact that it natively allows you to keep fiat money as a Stellar asset instead of exposing yourself to the risk of losing value to fluctuation. (Though there are caveats, but the infrastructure is there natively to build very useful things.)
I don't think this was quite bad a move as some make it out to be.
