First excuse me for my poor English. Wikipedia-Style Open publish (suggested by Mike Ciavarella) can be a logical solution for many of Current publication and evaluation system problems, currently we utilize popularity for “quality warranty” and “Ranking” of papers and authors. Such factor can be a measure for evaluating the papers and authors in the new style too. The reliability of papers can even increase by this way more, Categorization of scientific papers is one of necessities of today’s scientific network.

After I put down the phone, my heart never felt so heavy. I just called my parents in my hometown, Chengdu,  a city with 12 million people, which is just 90 kilometers away from the center of the strong earthquake at a magnitude of 7.9.  It has killed more than 10,000 people so far. The death toll is still rising hour by hour.
