I regret using the word "just", sorry for seeming negative. I only meant to clarify that this doesn't expose any information that YouTube isn't purposefully providing as part of the search API. I apologize for the confusion!
It's OK dude. If people deem a comment "derisive" just because of a normal word then this whole environment is quite insane. Don't feel bad for pointing out a fact. You did the right thing! If you pay too much attention to how the whole world is reacting to your words then you'll get absolutely nothing done. There will always be negative voices no matter what. The fact that your post is on top speaks for itself.
I don't think a "wrapper" is anywhere near the meaning of a "hack". Most of the things we see posted here on HN probably involve more work and creation. Not saying that such a wrapper is not valuable, just that I think this response just intends to point out a fact. To say it's a "derision" is way too reactive. So would you rather nobody point out the fact at all and just leave it be? That would be a far worse situation IMO.
