I love StumbleUpon:but I can,t get over the the overwhelming feeling that looking at ego driven young inexperienced bloggers who want to tell me what they know .What exactly do they know :not a lot.Creatures with the largest jaws in evolutionary terms,have the smallest brains. I would like to see imposing questions rather than slick answers.Ask and ye shall find grasshoppers! seek wisdom rather than dispel ignorance.
