Pearltrees 2 sucks! What do they mean by "Democratize"?
How to Burst the "Filter Bubble" that Protects Us from Opposing Views. The term “filter bubble” entered the public domain back in 2011when the internet activist Eli Pariser coined it to refer to the way recommendation engines shield people from certain aspects of the real world. Pariser used the example of two people who googled the term “BP”. One received links to investment news about BP while the other received links to the Deepwater Horizon oil spill, presumably as a result of some recommendation algorithm. This is an insidious problem.
Much social research shows that people prefer to receive information that they agree with instead of information that challenges their beliefs. This problem is compounded when social networks recommend content based on what users already like and on what people similar to them also like. This is the filter bubble—being surrounded only by people you like and content that you agree with. And the danger is that it can polarise populations creating potentially harmful divisions in society. It’s certainly a start. Pealtrees Users feedback.

Gallery — NetworkX 1.8.1 documentation. Pearltrees Radically Redesigns Its Online Curation Service To Reach A Wider Audience.
Pearltrees, the Paris-based online curation service that launched in late 2009, was always known for its rather quirky Flash-based interface that allowed you to organize web bookmarks, photos, text snippets and documents into a mindmap-like structure. For users who got that metaphor, it was a very powerful service, but its interface also presented a barrier to entry for new users. Today, the company is launching a radical redesign that does away with most of the old baggage of Pearltrees 1.0. Gone are the Flash dependency, the tree diagrams, the little round pearls that represented your content and most everything else from the old interface.
Here is what Pearltrees 1.0 looked like: And here is the new version: Pearltrees’ mission is still to allow you to organize everything you want on the service (in that respect, it almost competes with Evernote). 3. “We took what everybody liked about the old version and put it into a visualization that everybody could grasp right away,” Lamothe said.
