@jonah I do follow a few Substack writers through my feed reader, but I haven't really used the service for discovery. I'll have to give it a try.

I agree with Maggie that this is an issue for a lot of people, but personally, I've worked around it by following a variety of interesting people, newsletters, and linkblogs. I also keep an eye on sites like are.na and lobste.rs, where stuff I care about tends to bubble up. It does take more effort compared to just having everything handed to you by an engagement algorithm, though.
