This is funny...I just noticed something else while testing out this "spam free, no tracking" search engine. I clicked on the news link on blekko's search engine page. From there, I get a bunch of news web links returned...ABC, MSNBC etc. Then, from there, on the left side of that page, there are other options you can click, related to the list of news web links. Among them is one titled Local. I clicked it, and this "no tracking" search engine returned all of my local news web links.
Obviously, not quite the same thing as "tracking" per se, and I'm sure perfectly harmless to the user that "blekko" search engine nevertheless, knows where you are. I just thought it was hilarious that a search engine hawking the "no tracking" aspect, offers you a host of web pages from your home town. Google, the info sharing guru, doesn't even do that lol
