A friend of mine who did a bunch of mail based analytics phrased it thusly, "Let's say your in a meadow in the jungle, and you have just noticed that there is a tiger looking at you, are you safe?"<p>He was characterizing this move on Google's part as 'catching the gaze of the tiger' which is to say everyone knew this was going on, but nobody was doing anything about it, except now you know there is someone inside of Google thinking about this situation, gazing at it if you will.<p>They may walk away, they may not.<p>One of the more awesome things about having email re-imagined in a security conscious world would be that email would probably be unsuitable for collecting marketing analytics.<p>So far no one else seems to that done anything. Perhaps the tiger isn't hungry.
