I agree with Zoltan: the purpose of an RSS feed is to get updated, newsy content out to users (either in their own aggregators or as links on other sites). It's not primarily an SEO tool. If you don't have content that can keep being updated, it's probably not worth doing.

For your Egyptian example, you could do "New tour of Aswan", "Museum changes hours", or even "updated Luxor page".
