Or perhaps it is genuinely useful?

Music is an interest of mine, but not an active obsession. I've learned songs I want to play only through tabs, because every time I attempted to learn sheet music online, I ran away out of the fear of the heavy fog that exists in most descriptions about sheet music. Not to mention insufferable smugness, much like wine and craft beer snobs, about how sheet music is superior.

This guy, on the other hand, kept my attention, and described it in a way that I honestly found worth my time. I read the whole thing without wanting to switch tabs or multitask.

While there are some interesting parts, you have to filter the absurds like "C Major and A Minor are the same thing"

That's where the discussion right here on HN is helping :) One could argue that that is also a positive thing to have come out of the article having been written in the first place!

Indeed the difference between C major and A minor is the only really interesting thing I learned out of this post.

Which is great! That's why i read HN basically.

It's awesome that you're finding new things to learn. Honestly, reading sheet music is beneficial in a frightfully limited number of situations, and many many great musicians simply can't do it or find it a large struggle. Tabs are a wonderful entry point, I would encourage you to pursue learning by ear before reading. Keep playing!
