These days when you need to buy something new most of us will probably check out the web to see some reviews about the specific product to see if it will be a good investment or not... Pintarget is a project that will help you with your research quite good.

How it works: You create a Research folder first and you add all your bookmarks and pages to it. In the process of doing this the folder will learn about the things you need and find useful. From this moment that folder will keep looking and recommending information that is similar ,the cool extra you get is that it is also possible to make this folder public and share it with others who are interested in the same research...

Conclusion: Research done together so probably better then when you do it alone but also faster
