My problem often is that people/websites tell a lot but explain nothing on a subject.
That pissed me off way back when I was first starting with web technologies, as all the programming I'd done in the two decades prior it was all clearly and well laid out with good documentation.
These ALLEGED "specifications" and modern languages are some of the most poorly written CRAP, and most of the third party options -- books, tutorials, etc -- leave a lot to be desired.
I think it's why I stick with PHP as much as I do, as PHP.NET is some of the best documentation -- online or print -- I've dealt with since the age when a $100 Borland language included 20 pounds of books.
But no, today these half-tweet TLDR nose-breathers run around screaming "AAH!!! WALL OF TEXT!!!" at anything longer than a paragraph, then wonder why they don't actually understand how anything works.
Which is how we end up with people that think an orange moron with a 4th grade vocabulary is a "really stable genius", idiots eating tumeric as a cure-all, and women shoving jade eggs up the holiest of holies.
Enjoy our toxoplasmosis ladies!
Sometimes the stupid is so loud it's painful.
More so though, a lot of people say things without backing it up with examples, or even facts. It's how predatory scam-artist BS like "front-end" frameworks are media darlings even as they screw over site owner after site owner. People will spew a lot of praise and "glittering generalities" but be unable to explain WHY or provide legitimate examples to illustrate their claims.
Hell, half my articles on Medium could be summarized as "This popular thing and those promoting it are full of manure, here's why!" and in MOST of those it's because people make wild unfounded statements that cannot be backed up with by facts, but everyone accepts as true.
It's why I compare mainstream programming and many of the "accepted truths" as being more akin to cultism or the idiocy known as "faith".
