I just deleted the bookmark for Facebook so I have to type it in. Well, type "Fa" anyway. But just doing that instead of having a button to click cut down my usage by 70-80%. I was clicking the button out of boredom a lot, I guess.

I rarely use Facebook on my phone, I don't like the interface at all. Mostly I'll just use it to share a pic, and even then I'm going through Instagram to do it.
