I think you could add to your examples curation.

As shown by the gentleman that publishes HackerNews Monthly, there's definitely a market for the collection/curation of content, and that business probably scales pretty well.

There have to be all kinds of audiences out there that don't have time for a deep dive into the 'net to find the content they are regularly interested in, setup RSS feeds, etc. Bringing quality content to them that either entertains, educates, or enlightens (not to mention enriches) would seem to be a good business with a very good future.
