I'm too busy thinking of how useful it will be to *me* to be able to remember everything I did in the day, and the ability to go back and look for minor things that I didn't pay attention to before. Privacy is something to worry about, yes, but we all know someone will think of something as soon as it comes out.

I'm curious, how is it an issue?

I have a feeling I'm going to get flamed for this, but given that Google has been giving out free cloud storage, free word processing (on the cloud) and other nice things to have, is it an issue (Right now?) I mean, if Google actually uses my information for anything more than advertising, I would be kind of pissed, but I have yet to hear of anything like that.
