Google should really think about app selection on market by now.
Play store contains thousands of apps with millions of users using them, reviewing them. As an android user, I have liked, installed and using many awesome free and paid apps. I quite like the openness of Google, however I feel time has come to be selective on which apps to keep in the market and which not. It feels a bit awkward when I install a particular app and remove it soon I realize this is useless. I agree that Google might have their own stance on why still keeping these apps those are not much functional or buggy to some extent. We have to accept literally hundreds of different types of devices from different manufacturer has to be conformed with. Its a tedious job for Google Play store to conform with all these devices with different hardware and software specification, however there might an automated solution which works. Good thing is app reviewers are continuously making rating and writing comments. This rating and comments data could be used for keeping / ranking an app. Besides there should be more search filtering which might help users decide which apps to install and which not. Google play store may also keep apps installation, app usage duration and uninstallation frequency for rating an app.These are few wild ideas that Google might deploy in order to rank, keep, remove apps from Google Play Store.
