Sorry but because of the way Quora values privacy I don't really know which answers will thread on wrong waters so I'm just going to share this link:
http://www.quora.com/Why-do-some-people-in-Silicon-Valley-seem-to-believe-they-know-everything-about-users#
Apologies, if this reads like spam. Really I would like to quote several answers but I haven't figured out the best approach yet.
If you doubt my sincerity, please visit this link.
