Some people can't take the time to both learn and actually make a video for NESing, simple because they don't have the time. People have work, studying, and a social life to get to that leaves only a spare few hours for NESing a week, and they simply can't waste it on learning how to make a video. But I'll agree with you that most just aren't willing, and I think we are both in agreement that that is quite alright, so long as they don't characterize it as an inability.
That said, has it occurred to you that what you may characterize as "progress" isn't always the case for other people? Take your map comment, for instance. During the 3 years that mostly only one map was used in NESing there were in fact other maps presented, and if I cared enough I would dig them up for you. Among them Plexus redrew a map, among with bigger-then-necessary maps as well as smaller maps, and a map I'm using now in Superpowers. The main map was used mainly because it was the best map suited for the job. The other maps could have been deemed "progressive" but some people like you, but ultimately they failed to catch on.
So while your new maps may seem to you more accurate, bigger, and clearer, some may have a different opinion as to whether or not it is "progressive." I personally believe they are too big, and pay too much attention to detail that it makes it harder to update, and harder to read.
