You probably know from all of the pop-ups that Google threw at us in February that their privacy policy has changed. My take on this is that the consolidation of all of their services under a single policy is an excuse to get better marketing information on us as consumers, voters, etc.
Amazon and, to much lesser an extent, Facebook already have a marketing profile on me, and I accept that, but what Google is doing strikes as going against their claimed ethos of “don’t be evil.” So I’ve decided that I will delete my personal Google account, including YouTube. Most of the playlists I set up in there haven’t worked in a while anyway. My Gmail address is used only for Google Alerts, and I don’t count on them much anymore. I’ll continue to use Google’s search engine, but I won’t be signed in, and I won’t use the Chrome browser, because I’m going back to Firefox.
