Note still a looong ways from capturing the typical mainstream person who has no (even 2nd degree) relationship to crypto.
I'd speculate that 2nd degree connections are a good portion of the population as a whole...
I might agree except first we have to hurdle the problem that Steemit wasn't sticky with Asians (who live in Asia) and I believe ditto with Latin Americans, Africans in those regions. There is that one Chinese lady @sweetsssj who blogs daily.
Also Steemit wasn't sticky with the youth nor the middle-aged. The youth don't have the attention span for blogging (and that would to some extent include Asians, Latin Americans, and Africans since they are more childish and less sophisticated as evident by the TV programming). The middle-aged (e.g. myself) can't waste time on something not lucrative or important, unless it is for entertainment or philosophical.
You could easily just simplify this to say that it is [not] sticky nor appeals to almost no one at all!
