One of the things taught to undergrads in the humanities—specifically, in communications design—is that you should make the metadata of something interesting-seeming to a wider audience than the data it represents, so that it spreads further—that way, more of the people interested in the data will see it.

As an example, one of my friends told me about a very interesting paper called, and I quote, "Three Monkeys something something." He didn't know what it was about, but he said it "sounded like something I'd be interested in." He was quite right—but if it hadn't been for the monkeys, he wouldn't had anything vivid about the paper to recall at all.
