There is a "directory" of sorts in the works. @shivamshankars is compiling a list of the Twitter handles adopting Mastodon in the wake of the blocking of @sanjayuvacha's profile.

You can find the list here. https://docs.google.com/spreadsheets/d/19cRLIlvGcXXXbYQlTByqcVM6X2ZmnO2cfQBVBhXv0I0/edit#gid=429738813

You can also add your names there or ping Shivam with your handles. #India #TwitterIsTheNewOrkut
