Many sites around the web don't publish RSS anymore, and browsers have removed the default RSS readers.

That's "easy" in 2012: You Like them on Facebook (and wait for them to pay $$$ to promote their postings to get into your newsfeed).

As a user, if you want to get every posting from a Facebook page, you can select to be notified on all updates.

With a little work (not easy for people who don't care a lot about it) you can create an RSS feed for any Facebook page:

and then read that content in your RSS reader.
