How does the Substack App fit into the picture with apps like Matter and Instapaper (and their integrations with programs like Readwise?) Is this for the more casual / sane reader, and is meant to coexist alongside the more power-user apps like Matter?
Our ambition is to make the Substack app a great place to read, and as a writer a great way to have a direct connection with your audience. We have a lot of respect for apps like Matter (and Google Reader back in the day).
For now it's probably most compelling for folks who already do a lot of reading powered by Substack, but we're interested in adding more support for reading non-Substack things (and we already have some basic support for reading Substack stuff in other RSS readers.)
