An awesome video I found on www.Buzzfeed.com that shows how the things we do online would be SO creepy in real life.
PS - You know what I've always had a problem with? People who post a thousand pictures of themselves on Facebook and then actually take issue with the idea that someone might go and look at them. The person who looks at their pics is deemed "creepy". It' just not fair.. you put them up there!! Or maybe I am just creepy.
