Recently I have heard a few mentions about Google's "creepy" factor. It was mentioned on TWIG #63 and by Dave Winer from Scripting News. A friend called the other day, to discuss leaving Gmail for another email service. I asked what was the issue, he said he did not like Google reading his email. I pointed him to this Google page, he said it still felt creepy, that his email was being read, whether by human or bot.
