I'm glad to see that this was created!
There has definitely been more than one time where I had a friend who read an article that interested me, hit the "install app page" and closed the tab.
This is just another example of Facebook wanting to collect more and more and more data about us.
Ever since Facebook got more and more involved with the "app" fad, I used it less and less. Currently it tells me when events are, birthdays, and occasionally I'll browse some friends and see what's new.
Facebook left my focal point of browsing a long time ago, what about you?
