You might know Google owns YouTube, GMail, GChat, Google News, Google Docs and Google Reader, but the full privacy impact probably hasn't hit you until you look at the information from all those services condensed into one place, on this dashboard thing. Oh look, it's the last person you chatted with, the last person you emailed, the last video you watched, the last news search you ran, the last Google search, the last image search, the last video search, the last document you authored and maybe what you're buying your wife for Christmas.
