I think this is the same thing I was trying to address with this paragraph at the end:

> Another suggestion: provide browser extensions and iOS/Android sharing menu items so that it's easy to open an web page in the reading app. If there's one or more RSS feeds detected, throw in a subscribe button with checkboxes for each feed. The "shareable subscribe links" should include a link to the original RSS feed in the page metadata. Then if I click on the subscribe link but want to subscribe with a different RSS reader, I can do so easily.

i.e. we should be sure to provide smooth user experiences both for people who don't yet use a feed reader and for people who do. Agreed that Mastodon does this nicely, and I think adding in some browser extensions/mobile apps would help to automate things a bit more.
