Solid strategy and clear thinking backing it up - can attest to the fact that unpaywalled articles can get insane amounts of exposure.

I've seen it with a few other unpaywalled creators who have meteoric numbers - Smoul and Remi are 2 such (worth checking them out for ideas and inspiration Gabriel).

Good luck and Godspeed with your goals and journey here!

P.S. Keep up the book listicles, I love how non-cliche they are.
