I found this talk intriguing....... and it's mercifully not too long.
As web companies strive to tailor their services (including news and search results) to our hyper- personalised tastes, there's a dangerous unintended consequence:
We get trapped in a "filter bubble" and don't get exposed to information that could challenge or broaden our worldview.
So Google is influencing all of us by determining what we need to know without giving us choice.
Eli Pariser argues powerfully that this will ultimately prove to be bad for us and bad for democracy.
If anyone wants to try an experiment please let me know in the comments box:
The experiment is that we do a combined search for some mutually agreed phrase and compare what we get.
