Hahaha! "Want more!"
The gaming industry evolves, and the expectations of newer generations of gamers also evolves. I don't expect kids nowadays to have a good appreciation of older systems because they didn't grow up with it. Like, I grew up on NES and forward and talk to my friend 2 yrs younger, and he grew up on SNES and forward. My family even had an Atari 2600, although I don't remember much about it. But having that background adds so much more enjoyment to seeing a TAS, much like having actually played the game.
A quick note regarding grassini's comment about the correct audience being actual players. Non-players can also weigh in in terms of entertainment value. But, given NES limitations, the game genre, and many other points brought up in the thread, it would probably be biased towards rejection by non-players.
And here are my two cents to the whole arguing. The TAS community is founded on improving upon constructive criticism and bettering itself and its products. Any improvement or piece of advice towards improvement is highly valued. IronSlayer's initial comment was just a gut reaction (which wreaked all the havoc) that provided little to no insight (Iron later stated that he understands the NES limitations, which would have not caused an uproar if it replaced his original point). His 2nd point about boring and repetitive is valid; the 3rd about no skill stems from the goal choice. Netiquette is most likely the norm in this community due to its purpose. If someone chooses not to use netiquette, just nudge him/her towards that direction by clarifying the statements made. Responding emotionally will just feed the fire.
(Plus, you can slowly brainwash--I mean condition people to conform after enough time has passed, hehehe)
Hope I didn't misinterpret my understanding of the community, as I just lurk and read most of the submissions.
EDIT: And reminiscing of Atari, I found this:
