I've no problems mapping some concepts to resources like the classics article, post, person, event, etc... But some aspects of a WebApp I find no REST answer, like a "homepage" which shows a summary of the latests articles, posts and events in the site. It's not about 1 resource or a collection of resources of the same kind, it's about a bunch of different resources.
In this case, your homepage is a resource which summarizes the latest changes to the articles, posts, and events resources. In this case, GET is a meaningful request, while POST, PUT, and DELETE are probably not. Your dashboard resource probably acts similarly, while your "about this site" resource probably behaves more like a traditional static file.
