Google Docs basically crawls everything you type into it and uses it to profile you. It’s in their TOS.

I think that’a pretry bad, but that’s what you get for using a free service, you’re paying with your personal information (and possibly that of others).

I can’t deny it has some useful functionality, but I just don’t need most of it personally. I don’t think you need it for 99% of your usual work.
