Having said that, I can see how it would be hard to go further; it must be relatively easy to both identify people, places, movies, etc. in a text and to locate pertinent data for them out on the Web. It's much harder to do this with historical events, intellectual currents, literary tropes, and so on. The Web is still an ontologically simple place.
I would personally see Small Demons as a fun research and exploration tool, sort of a very special kind of concordance. I could see literary scholars of the "distant reading" school popularized by Franco Moretti finding some use in this. I really do think this is cool.
