I actually do open the app store specifically to find a cool new app to install. I do this maybe a couple times a year.

It never works. The apps it suggests are all ad farming garbage. I have found maybe one fun game doing this over the years, but mostly its been repeated frustration. I keep doing it occasionally in hopes that I find another diamond in the rough but I think Google has just trashed this whole thing up.

There is probably a set of users who download tons of apps and throw money after them like crazy, and that's probably what Google has optimized for.
