Yeah seems pretty stupid to me. The best use would be to store hashes that convert to anything. A hash can convert into an entire book for example, and you can store the hash string for peanuts.
Pretty stupid is that you don't understand hashes. A hash - doesn't 'convert into an entire book' - or anything.
How did the community get so many dumbasses?
One thing to remember is that as Bitcoin is adopted more in the mainstream, there are going to be more people that don't understand basic crypto. Sad? Yes. Inevitable? Also yes.
