Feature Request: Automated search for friends

I toyed a bit around with the Keybase API to help me find people on Keybase who I follow on Twitter since entering every name in the search bar by hand is a bit tedious... And I was kinda successful (https://github.com/dtiersch/keybase-friendfinder outputs a list of keybase usernames which have Twitter accounts linked I follow)

But this made me wonder if such a feature could be made available directly on keybase.io.

This would mean that keybase provides OAuth logins for various services (e.g. GoogleMail, YahooMail (for Email Addresses), Twitter (for followed accounts), etc.) with which they would have access to the contacts so that they could in turn search for matching data in their own user base.
_for illustration: the feature on last.fm:_

Start by reviewing the linked keybase-friendfinder project and the Keybase API approach described in the issue. The issue names no repository files, tests, or implementation entry points, and it does not define a concrete completion criterion beyond OAuth-based contact matching across services.
