Laserful

Virtual Journal of Laser is a web tool to help laser researchers follow publications from major academic journals. It automatically aggregate updates from Physics or Optics journals. Only abstracts of articles that are directly related to laser are imported into the system. By voting, commenting and simply visiting, interesting papers will be promoted and become more visible and easy to find.

It has been rebuilt, now one can vote on papers to promote them. It can sort popularity of papers with an algorithm similar to "radioactivity". I use it for checking new papersr and see what other people are interested in.
