I have an "in" on HackerNoon, but not all of my content is tech/startup related (which is what they want). I think the problem is that platforms need a way to monetize, Medium was great during it's growth years but once it needed to start making money, how do they monetize? I'm still hopeful for something else out there
I think the biggest problem with Medium is the fact that nothing was paywalled and then they introduced the paywall, which caused frustration. Substack, on the other hand, is much more pleasurable because there is an expectation from the start that some of the articles are going to be paywalled.
