I only really go the youtube route, but I access it through a third party app. I also use facebook, but I'm not on there a hell of a lot. The one site I'm on the most is tumblr.
I only use a couple of "apps". For the most part "apps" just hog resources and space for things that could just as easily be done by going to website itself. Plus grant way to many permissions. I honestly don't see the lure or need for 99% of them. Ones like the youtube "apps" are especially dumb since it usually means limited access and decreased functionality.
Ever wonder why your devices battery life and speed turned to chit? It's all those silly apps that can be done away with by using your browser.
