I've seen numerous prior posts where people have been critical of 3E by saying things like their "eyes still bleed", or their "heads ache" or they "wake up screaming" when they just think about DMing 3E. (I've actually seen all of these statements, amongst others). It boggles me. These people are insulting themselves. They don't seem to realize it.
If someone walked up to you and said that just thinking about algebra made them wake up screaming, I think you would assume this person sucks at math. They may be competent at basic arithmetic. But they are not going to be the person you want teaching your kid even the parts of math they do get.
AllisterH (and others) are essentially saying that 4E is good because it is basic arithmetic for the guy whose eyes bleed over algebra. I find that insulting. Now, I'm fully certain that this isn't the beginning and the end of what AllisterH would say is good about 4E. It was simply the topic of the moment.
I would think that person doesn't want to spend their free time doing complex mathematics, just like I don't want to spend my free time trying to figure out what every feat does on a monster that is in a module I'm trying to run. I just want to roll some dice and have some fun, which for me includes not having to learn a complex system that I don't see much value in. I am not insulting myself. Instead I am rewarding myself for finding a game that I get to have fun in.
Also, as much fun as analogies are, I really wish people would avoid them. I have yet to see one that actually convinces anyone, instead it just seems to entrench the two sides of any argument even more with their implied value judgments.
