Most people don't understand just how pervasive the data mining is.<br>
Every time you go to a web page that includes the little "like me"<br>
buttons or has a Google search link, or other reference to some other<br>
service, it usually means that your browser had to go to that remote<br>
web site to retrieve some data, maybe just the logo. But the remote<br>
web site can capture your IP address, possibly your MAC address, and<br>
anything else it can request from the browser, and put it together<br>
with all the other info they can capture, retrieve or deduce, to build<br>
a profile of your browsing habits. Maybe they left a cookie on your<br>
system from the last time you were there? Depending what sites you<br>
frequent, they may be able to link it to you as an individual instead<br>
of just a general age bracket and gender.<br>
<br>
It is pretty much impossible to avoid completely, but I don't have to<br>
ask for it by joining Twitter or Facebook. And then of course there<br>
are the people who do everything but post their social security number<br>
on the web site....<br>
