@ken_b -- so far it's been mostly ixquick and duckduckgo that I've been promoting .. I never have liked the so called Filter Bubble Of Personalized Results that is Google -- Even whilst signed out, the tracking via IP that Google does is a pain. I get tired of looking at the same stuff over and over again.
I know that Google's search numbers are huge, but I'm wondering how much of a hit those search numbers would take if Google wasn't "forcing" the use of it's properties ..
In the end, it all boils down to whether or not you prefer to have someone else do your thinking for you .. I don't accept 3rd party cookies and clear cache and cookies after every browser session. I also use the Ghostery and others on occasion .. The results in Google are wildly amusing, while the results in duckduckgo, and ixquick remain fairly consistent.
