I recall seeing something of this sort happening on goog for about 12~18mo - every so often a researcher post does the rounds where someone finds Yet Another way goog is fucking it up
the advertising dept has completely captured all mindshare and it is (demonstrably) the only part that goog-the-business cares about
sidebar: I definitely wouldn’t be surprised if it comes to this overall being a case of “a shop optimised by tuning, and then it suddenly turns out the entire industry has never tried to tune a thing ever”
because why try hard when the money taps are open and flowing free? velocity over everything! this is the bayfucker way.
