Interactive PLoS website for scientific community

I just came across PLoS (Public Library of Science) website http://www.plos.org/index.php
It's an amazing site whose objective is to make the scientific literature available for free to the scientific community. Of course, you will have to pay if your article is accepted in their journals. The following are the core principles of PLoS: (Modified from their website)

1. Open access.
2. Excellence.
   
3. Scientific integrity.
4. Breadth.
5. Cooperation.
   
6. Financial fairness.
7. Community engagement.
8. Internationalism.
   
9. Science as a public resource.
   

They have seven journals that have good citation index. They are
1. PLoS One
2. PLoS Biology
3. PLoS Medicine
4. PLoS Computational Biology
5. PLoS Genetics
6. PLoS Pathogens
7. PLoS Neglected Tropical Diseases
