Although there are probably a few, it's the wrong question, IMO.

To find the revolution, what authors are:

a) Banned from making Twitter threads

b) Think asking people to 'subscribe to my substack' for the cost of a meal per day is offensive and/or disagree with Substack's user agreement and/or haven't the 'clout' to draw income with a paywall

c) Aren't being found on Ghost.org

d) self-custody their independent, free writing, and therefore are banned from the network effects of ever having a chance to be found on a search engine

e) work at centralized archive companies/services / National Archives

f) create scholarly articles yet understand that the gatekeeping peer review process is corrupt

Or if you must chase those who are already successful in a paradigm that does not reward free thinking,

- successful bloggers who can crosspost to nostr for mutual benefit
