Despite having tons of stores of all sorts (app stores by microsoft apple and google, movies streaming stores like netflix, game stores like steam, ...) no one has truly found a way to solve the discoverability problem that feels really satisfying.

Some are decent, but that's mostly by sending you so many stuff at once that a few are bound to be acceptable, but that doesn't mean they were the best choices for you (eg you buy that game or look that movie, but there are other stuff you would have taken over it if the store had been able to identify them).

Job/recruiting is even harder in that it's a two way attraction, the employee need to convince you but you need to convince them back. Result being, we self impose the same "spam" of propositions by seeing tons of candidate / interviewing in tons of companies, wasting a lot of people time (let's face it, in a big share of interviews either if not both of the parties knows it won't fit after just a couple of minutes).

I have no doubt that companies who are not merely looking for marketing / reselling gimmick have a share of that space to own, Google or not.
