Long before David Letterman immortalized the Top 10, publishers figured out that readers love lists.

Magazine cover stories rank the best places to live, the best places to do business, the world’s richest people. The internet, of course, is a bit more creative. A quick Google search for the phrase “top 10″ yields, after Letterman:

· Top 10 naked people on Google Earth
· Top 10 ways to destroy earth
· Top 10 urinals (somebody’s doing some serious SEO here)
· Top 10 strangest Lego creations (ditto)
· Top 10 spammers
