Facebook sucks, no really, it sucks you in. It plays with your brain and lures you into not being able to do without a little peek into the white and blue for a sign of some red on the top.
The world of Facebook is like a hypnotized parade of familiar faces walking by on the street while you stay focussed on your work indoors. Their movements and existence is of common knowledge to you and hence that one peep out the window to look at the mundane parade is inevitable.
If Buddha were to know of man’s craze about Facebook and inability to detach, He would be grossly disappointed in the lack of self control.
Facebook is great for a lot of things, but it being an inadvertent alternate for an ‘effective’ utilization of time, is pure unhealthy and sad.
