Mastodon uses Blockstack?

#1

Mastodon is listed as a Blockstack app but I don’t see that it uses Blockstack:

EDIT: Ah, looking closer it seems that app.co lists all dapps, not just Blockstack dapps. Is there a way to view a list of only Blockstack apps?

#2

You can do app.co/blockstack that will list app using blockstack.
