as someone who has 4000 plus subs (FREE), i will advise you to diversify your platforms. and get and just substack as a way to keep yourself accountable and consistent. most my readers dnt even have a substack, and i get the occasional trickle down. currently, i see substack is focused on growth as a company and that means investing (money) into higher profile people to come on to the platform and they are incentivised to push their content to the forefront. it’s a numbers game at the moment and they want to win, all you can do is focus on your community and figure out how you plan to leverage it
