Every single of those webpages have an RSS feed.

I agree with him, I consume most of my news using RSS and even in pages that do not have RSS (like soundcloud) there is a RSS server somewhere serving the feed.
... however, they do 'touch' a lot of the articles during the week so the order they appear in the feed keeps changing.
