Filter Bubbles: personalization algorithms

Filters Bubbles, a term coined by Eli Pariserm, is basically the culmination of personalization algorithms that are present though out the internet; most notably on sites as Google, facebook, and twitter. These algorithms take note of habits on the internet and attempt to create a web experience that is curtailed to your likes and interests. Sounds like a good thing perhaps, but as explained the inherently mathematical algorithms degrade the diversity of information and isolate the user from potential useful or insightful information.
