Jack, I installed the Yarns Indie Reader just minutes ago. Setup was easy and of course, I used your site as the first test. Love it! This is a useful contribution to the IndieWeb.
I have hundreds of feeds in my RSS reader. Have you done on test on how/if performance is affected? At some point I need cut back on my RSS list.
Does the plugin support Markdown for formatting?
Looking forward to how this develops.
