Perhaps you've read that Google will drop their RSS services and also
RSS chrome extension.
I want to inform you about how MediaWiki can help.
+
https://www.mediawiki.org/wiki/Extension:RSS
consume RSS feeds from elsewhere and render them one or more MW wiki pages
+
https://www.mediawiki.org/wiki/Extension:WikiArticleFeeds
generate RSS Feed(s) from content of MW page(s): authoring feeds by
editing a MediaWiki page
I maintain both extensions and made them compatible a while ago, bot are
in git/gerrit.
Documentation is up-to-date, and they run with MediaWiki latest versions
(i.e. core master).
Before you ask, yes, you can render feeds in a MW using E:RSS,
which are generated in the same or different MW by using E:WikiArticleFeeds
