No idea how this is getting so many points. There's absolutely nothing of any practical interest here. Use version control and documentation... End of post. I'd say these are more industry standard practices than leading edge.
Because the basics have to be pointed out again ... and again.
I think the upvotes don't primarily mean "omg I never thought to do this" but rather "will someone please staple this to the foreheads of all the clueless devs I've had to clean up after."
Yeah, that's sort of what "best practices" are all about. They are for teaching outsiders what insiders have learned through practice. The intended audience is everyone who doesn't already know this.
If you consider the article of no practical interest for a seasoned insider, that's about the highest praise you can give.
Not to mention those points were mainly subjective. Don't get me wrong, I like and use Git myself but statements like "Use this, most people use it so you must use it too!" are just horrible.
