[Web4lib] Filter Bubbles and Libraries' Public Computers?

[Dan Ream]

Web4Libers-

I've been reading and viewing with interest about Eli Pariser's book,
"The Filter Bubble: What the Internet Is Hiding from You" and highly 
recommend
his 9-minute TED talk summary about it at

http://www.ted.com/talks/eli_pariser_beware_online_filter_bubbles.html
(also on YouTube).

I don't recall this being discussed here before on Web4Lib, but if it 
has already,
please point me to that discussion.

My questions concern how do the personalized search features that 
Google uses
effect the shared public computers in our libraries. Beyond personal 
search
history, Pariser estimates that Google uses 57 criteria to shape your 
results.
Google hasn't publicly shared what those 57 are, but here's one search 
expert's guess..

These are thought to include browser type, computer type, and many 
other factors
that would seem chaotic, but influential to search results on a shared 
public computer
in a library or campus computer lab.

Beyond the obvious difficulty this presents for teaching librarians to 
explain how
Google results are found, I'm wondering what steps a library can take 
to reduce
the personalization functions of Google so that your next Googler's 
search results
aren't overly influenced by the twenty others who last sat at that 
same library workstation.

Thoughts or suggestions?
