I wonder how people searching the web come across the Sermonindex site? Google and Yahoo search engines both give different search results to different people that use their search engines?Do you wonder why people that post to your facebook tend to think as you do? Facebook edits (eliminates) replies to your facebook postings from individuals who do not frequent sites you frequent? This is called personalizing.This cannot be good.See/listen for yourself: http://www.youtube.com/watch?v=bOE1HFEL8XA&feature=shareIf it is unacceptable to post this link, search YouTube for "What FACEBOOK and GOOGLE are hiding from the world" OOOPS! Hopefully YouTube is not using an amoral algorithm "within site" to edit what you search for.
As far as I know, www.duckduckgo.com is the only search engine that does NOT track you.
THANKS FOR POSTING! This is very informative and helpful.
