Considering all our communication is written down, with our names mere inches away from our posts, I consider Ben's "Proper Noun Anomia" excuse to be pretty weak.
It's like having a dictionary next to you, and then complaining when people use big words you've never heard before. I can understand if you're in an IRL conversation, and you can't recall who said what; but when you have an unlimited amount of time, all the resources in front of you, and you're still too lazy to look it up, and expect us to give you a pass, well...
