I couldn’t find any existing discussion about a Medium alternative - apologies if I am just suffering from Domestic Blindness . .
I have been using Medium for some time and it does have many attractions - but there are also some annoyances - some of which could be fixed in an equivalent SAFE app. Of course the main issue is the Network Effect - M is already solidly in the space . . even so, I think a SAFE version would do very well . .
