Are the BibCharts a ranking?

The BibCharts are no rankings, but an overview, which lists libraries that are active on the social web. The objective is to achieve greater transparency: Which library is making significant gains in community size? Why are some facilities more represented on Twitter than on Facebook? Through the BibCharts such movements can be displayed, so that other facilities can learn from it.
