Hoi,
I do not know if you have seen the statistics compiled by Magnus [1]. They
are up to date and useful.
I blogged about it [2]. As far as I am concerned, the biggest challenge we
face is the lack of labels. Given that 280+ languages are represented in
Wikidata it clearly demonstrates that Wikidata is useless as it is for most
languages. Please tell me that I am wrong and explain why.
Thanks,
GerardM
