Welcome to the evil empire Jerry!

Knowing how careful Facebook and its apps have been with user data in the past, I'd caution against installing anything unless you know what it is, and actually have a use for it. For example I find the messenger app useful on my phone (for facebook messaging), but I think I've removed virtually all other apps that I once had installed. It was kind of fun to play scrabble with old friends on the other side of the world way back when, but whenever you install something, you give someone permission to do stuff with your data. Not worth it in many cases IMHO.

However, that having been said, I find facebook extremely useful, particularly for keeping in touch with friends who have scattered all over the place.

Enjoy, and good luck avoiding the garbage.
