They were always junk, full of formulaic, self-promoting, astroturfing trash. In most cases, it would be more appropriate to view them as content marketing (c.f. digital pollution), not actual developer resources.
Very variable quality, I agree. But even an astroturfer has to throw in some actually useful tools in there to give cover for the payload they're promoting.
Completely disagree. When AI was new I found so many great tools through awesome-* repositories. There was some of that going on for sure, but most lists were a curation of good tools.
Same with newspaper, ALWAYS been full of JUNK, they never started out well, got exploited and now wildly different than they initially were.
I disagree with the blanket statement. Lists like awesome-scalability [1] are actually pretty useful and full of great references. They dont recommend any specific tool, and it is a very good resource to learn unknown unknowns.
AI suffers the same problem Search Engines had: you cannot ask about something you dont know. Thats why monthly magazines were great: they pushed" knowledge to us so that we learned things we didnt know existed.
