I understand your very valid concerns,
kartal. Google took a decent step this week by creating a
dashboard for users to control how much or little privacy they want to share. Dashboard is more of an info aggregator, but at least gives us insight into what information that Google has on us its databases, and gives us the opportunity to change privacy settings and to delete services we don't want anymore. However,
here is what Dashboard doesn't reveal yet.
Since anyone -- if they really want to -- can follow me online and track my movements, purchases, emails, key inputs, passwords, etc., it's important I practice safe computing, but much of that starts by
not using Windows to surf the web with.
