Ranking research seems to be continuously on the table nowadays. In my country academic community came up with [a website][1] that ranks publication forums in scale $1$-$3$. 

One may always argue about this kind of rankings and their relevance to science, but now that they seem to appear anyway I would be interested to learn what other rankings are available in the internet that would be relevant to a mathematician?
