The author seems to be mainlining Luke Smith's kool-aid (I think he runs landchad.net). Even though Luke is clearly intelligent and occasionally makes a good point, he has a habit of draping everything in this weird alt-right-esque meme-language that makes it all fairly hard to swallow, although that may well be the point.

How old is that guy. I can’t help but get “fellow kids” vibes from him.

Apparently we're not the target audience.

When I got to "I write a lot.", my first thought was "That's a shame."

Not my proudest moment.

After stepping back for a minute and assuming the author is reasonable, I'm left to conclude that he made a strong choice to speak to an audience that he felt like he could and should reach. If that's true, and that voice is the way to reach them, then it's also possible that the target audience is turned off by the sort of voice that would reach me.

There are a lot of assumptions there, but I would also be making assumptions if I were to go with my initial thought.

I think it is the use of the term "landchad". I've never heard it before. Maybe it's a thing, but it sure sounds like a phrase from the incel world.

Actually kind of agree. Need to go through revision. Sentences feel unnecessarily long and drawn out.

I'm not sure "long sentences" is what the GP meant.
