Wait, what's the point here?
Smaller organizations can't afford to just play a numbers game and bank on hires being good enough to fit in somewhere.
Plus where else would you show off your collection of pictures you have of yourself eating ice cream?
I read an article by a Netflix hirer who basically bragged about how arbitrary and capricious their hiring was. "I noticed most of our staff were musicians, so I made sure to hire plenty of those, too, and they did great." People in my cubicle block have names with N in them, too, and we seem pretty good too.
Honestly, it sounds cynical but I think that's the primary reason people write these articles, to appear to be thought leaders when people search for their names.
But good on them, I suppose. It is useful to share ideas, and eventually the good ones will percolate up to the top (hopefully).
You need to filter more :). Good technical articles don't read like self-promotion, but more like someone discovering an idea and playing with it, or someone explaining an idea in detail, describing relevant trade-offs.
