> “Honestly,” one 15-year-old girl told Pew, “I'm on it constantly but I hate it so much.”

Maybe I'm too far from high school but I can't picture a situation where you would have to use FB "constantly" even though you "hate it". It's not really explained in the article either, there's just some superficial quotes about "Drama" and "Adult presence".

I know adult's who say they hate facebook but maintain accounts but this equates to logging in for a couple minutes a couple times a week, liking some photos, maybe posting a few and then getting on with their day.
