I received two of those zapvertisements and it was lost on me. Only realised what you were doing now after seeing this note boosted by someone I follow.

I also only follow my followers because I believe that it would give me a more diversified feed and less curated set of opinions protecting me from falling into a trap of confirmation bias. (Which I realise now is unlikely.)

I don't know if this feedback means anything to you. Maybe there is an untapped minority target of your experiment you don't know about or something.
