Thanks - I look at Medium through my phone and laptop. I’d be curious about the relative size of the Substack audience.

Substack seems to be favored by professional writers, but Medium appears to be superior in a variety of ways- but I can’t tell if it is 1) merely because I’ve used it longer and understand it’s features or 2) the people I’m following Substack are covering a different range of topics (and the Substack people often annoy me) or 3) the platforms really have different functionality
