RSS onboarding is a struggle for new users. RSS, unlike commercial products, lacks a "front page" to explain the benefits and how to get started.
Two things that can help:
1. Have a prettified RSS feed that tells new users what it is, rather than showing raw XML. For example here's mine: http://interconnected.org/home/feed
2. (plug) Link to https://aboutfeeds.com which is a one-pager RSS explainer site, providing links to newsreaders and simple instructions on how to subscribe.
This is really cool, will have to add that to all the feeds I host. Too bad browers can't display RSS feeds themselves anymore without manually adding an XML stylesheet - Firefox used to be able to do that.
