It’s always depressing to see people give bad advice. It’s even more depressing to see people eat that bad advice up and say things like, 'This is really good and totally right!' Now, I don’t like starting arguments on the Internet, so I normally just shake my head and look the other way. But this is something I have seen more than a couple of times from people who have a greater audience than next to none, and this is not a good thing.
So! Time for another essay, I think. Show vs. tell.
