Hi sbray1834, the Reader view is limited in the kinds of pages it understands. It scans the HTML code of the page looking for certain structures similar to articles or blog posts. It has a plan for how to simplify those. But if it doesn't find the kinds of page structures it is designed to handle, it just gives up.
