It should be explained more, why would you want to explain it less?
Because we don't have an infinite amount of time. Every time we type AA instead of antialiasing, we save time. Every time we type antialiasing instead of its definition we save time. If anyone doesn't understand any of these terms, and for whatever reason can't find the definitions, they can ask, and we'll answer, losing the saved time. But then they'll never have to ask again saving time in the future.
When things takes less time to write, we're more likely to write them. Having to explain every pixel art specific technique in every post would certainly make me less likely to post.
Tetris is much less interpretive a medium than art
Granted. But I said EVERY niche group, just used Tetris as an example. How about various law terms, psychology terms,
anything else terms? They all exist for the reasons I stated.
Hue-shifting doesn't represent something that is made up
Then why do you question the validity of its use?
so those who could learn more without the term may be encouraged to follow it blindly.
No more so than almost any other term, in any other thing. Using lots of contrast ain't
always a good idea, nor hue shifting, nor avoiding tangents. I'm not sure why you take so much issue with this specific term.
