On Keybase profile page, indicate if public key is part of the "strong set"

Keybase user profiles show the public key - it would be useful to know if a key is part of the "strong set" of signed / trusted public keys. It could simply show the results of a system such as the one at http://pgp.cs.uu.nl. I would suggest that the profile page should displaying a message if a key is part of the "strong set," nothing if not - with perhaps the option to display additional information on the place of the key within the web of trust, for example the mean shortest distance and the number of signatures on the key.

See for example: http://pgp.cs.uu.nl/stats/FC243F3C.html

Start by reviewing the Keybase profile page and the linked PGP strong-set example to understand the proposed trust information. Define the display scope and acceptance criteria for showing strong-set status and optional web-of-trust details; completion requires an agreed design and implementation plan.
