I was just scrollscrollscroll-ing. I find that based on my mood I either am completely unsocial and scroll through everything but the handful of people I know; or I'm excessively social and I'm all "75 percent of this is great! Why don't I read everything all the time!?" And then the next day I'm back to scrolling.
I guess sometimes we just can't handle all the stimulation.
I get into the scrolling mood at times too, but after I've mindlessly done it for a while, I realise I have just wasted a lot of precious time!
