My goodness, these hit counters can tell you so much these days ... I'm amazed at the spying and counter-spying possibilities on the internet!
The thing is I recently stopped giving a damn after being paranoid about it when I was on orkut and irc. (Sometimes hanging around with kids in their 20s and their companion young-moms means that *you* get to listen to everything *their moms* have dumped on them - including internet 'security'/paranoia-country.:)
If you aren't using a credit card online, dropping your namecard in every site, I think you're secure enough like we believed in the 90s.
