Thanks a lot all who are involved, very interesting.

However, when I look at the statistics of usage,

http://wdcm.wmflabs.org/WDCM_UsageDashboard/

I see that Wikivoyage allegedly uses, in particular, genes, humans (quite a
lot, actually), and scientific articles. How could this be? I am pretty
sure it does not use any of these.

Cheers
