Last year my sister tried to get me on it; it really made me anxious just because of ALL the endless amounts of stuff you can look at. I wanted to just look and look and look. My brain was frying from the excitement of overstimulation, my ocd just couldn't take it!
So I looked last night and kept looking until it was 5 A.M.- couldn't turn it or my brain off. Ohmyshit it was too much. But I love the damn thing.
