Looks like Facebook has created a feed that shows updates from all the pages you like (like your News Feed, but for Pages). Naturally, it's called 'Pages Feed'
You'll find it on the left hand side of your Home page in your 'Pages' section, but if you click the little 'pencil' image, you can add it up top in your 'Favourites' section – making it easier to notice / remember that the feature exists. Which will make it easier for you to keep up with posts from the pages you like.
Seems like a (small) step in the right direction after all of that 'promoted posts / EdgeRank' jibber jabber that has been flying around lately.
