Jeremy Smith of Hacking Christianity has recently written about how search engines (Google and others) can create an echo chamber, in which people doing Internet searches actually shape what will be found by subsequent searchers.
Okay, some of you may immediately understand what I just typed there, but I didn't. If you're like me, take an extra measure of patience and work your way through this piece. To whet your appetite for it, I'll give you the sentences that really got my attention:
I'm not wearing a tinfoil hat, this is happening today. Search for the United Methodist Church on Google and the Wikipedia entry comes up #1 (ABOVE the umc.org website! Seriously!). Thus the publicly editable website is above the UMC-written doctrine.
One mention of a tinfoil hat, and you have hooked this here reader, Jeremy. See his whole post here (it includes links to previous posts that lay the groundwork for the ideas he presents). Lots of stuff to consider.
(Interestingly enough, tinfoil hats have actually been proven ineffective. Might be helpful to know that someday.)
