You took the very words right out of my mouth. Jokes aside, TILs are not necessarily just junk food. As a reader, oftentimes I find them akin to hors d'oeuvres that whet my appetite for something other than what I'm diving into at that period, a sort of inspiration. Sure, many of them may turn out to be low effort blog fodder, but that usually has to do with each individual source's quality - in which case they help filter out low SNR sources. Of course, when I have TIL-style moments myself, I jot down a quick note, usually ending up fleshing it out later, as I expect many other engineers do. I prefer having a low effort aide memoire for later, rather than an open browser tab or bookmark that I'll almost certainly forget about in a few hours' or a day's time.
