Substack is also a way to financially support writers and artists who have been pushed out of traditional media, or are too niche to fit in mass market publications.

It would help writers and readers if Substack bundled groups of writers together, perhaps by genre/type/subject like a magazine, and for the current cost of one subscription newsletter have 5 newsletters that the subscriber/paying customer can choose to assemble to create their personal "magazine." This would allow the reader to financially support more writers/artists, which would allow more of them to continue publishing their work and grow.
