Has anybody used #Glottolog data?

It is a database of languoids, that is, it contains information on dialects, languages and language families globally, their geographical "ranges", and inter-language relations, and has potential for some pretty cool analyses. Awesome #OpenData for sure. However, I am unsure how it compares to #WALS or #Ethnologue data.
