Google is nobody's friend, unless you like having someone accumulate data on everything you do on the 'net.
Yeah, and that's why I asked Kim earlier today in a reply if a button with an "f" in it had some Facebook function. It did. I had heard a tech. interviewee a day or two ago talking about the information that Facebook was collecting on its members. One guy (and probably the last one) asked for a copy of his data and eventually received a CD with over 1,000 pages of data on it, including the geographical area he was in when he visited different websites. He said that now when people want to see their data they're directed to a web page that has a small fraction of the data that Facebook collects, and it only contains the data that they'd be able to look up on their own.
I know this is OT..
But you do realise (I hope) that apart from some tricky JavaScript and php code, 99% of tracking is done with cookies - if you delete cookies when you shut down or use FFox's private browser sessions then they can't track where you've been and where you go.
Some small tracking is done with java/php or referrer code, but this is usually only one site-to-site layer, not across multiple sites.
Delete your cookies and all that's recorded is just that one site access session, not where you go or where you've been.
Now-a-day this shiit is important!
