Hard to believe it is the best possible video search implementation for their ad serving goals.
Youtube was in this business from day 1. Even before Google. Youtube was never going to be anything other than an ad-platform with videos to lure in the products.
Vid.me tried to be a video platform with videos to lure in users, but it went bankrupt, because nobody wanted to pay and nobody wanted to watch ads.
the unrelated videos it shows me are so far from anything I'm interested in that I can only conclude it's showing both of us the same stuff, just lowest common denominator popularity.
>videos I'm also interested in, sometimes more than what I'm searching for
therefore, based on my argument, you must have horrible taste
