I don't know how many of you follow the Wikimedia blog, but few days ago we got posted:

The good thing is that the survey link was there so right now we have more than 70 surveys completed. 

The bad thing is that many wikisources did not propmote the survey in their village pump/sitenotice. 
Could you please check your own Wikisource and paste the link?

English, German, Spanish sources don't have it. 
I can't check myself Ukranian, Russian, Hebrew and Hindi though.
