Some quotes:
Alas, before my car left town editing dropped to zero, and no single edit has been performed on Wp/hz ever since. Which is, in a nutshell, the story of all my outreach in Namibia. Operation successful, patient dead: A well-run workshop resulted in exactly zero new editors, zero subsequent edits, zero subsequent picture uploads. What I did get, however, were several sms from attendees, asking to have such an enjoyable workshop again soon!
Punchline:Building on anecdotal evidence, outreach workshops have not been successful anywhere. Some simple number crunching gives you one idea why: English Wikipedia has attracted about 3K very active editors (100+edits/month) and some 30K active editors (5+edits/month), out of 1.5 billion speakers of that language. Per million speakers, this is about 2 very active and 20 active editors. Proportionally, Somalia has more doctors than the world has active Wikipedians. There are more professional chess players in the world than very active Wikipedians. Wikipedia is a hobby of a tiny minority.
I have little knowledge of the whole business of workshops, but it's almost as if publicity is a goal in itself for the WMF, and the volunteer base isn't even an afterthought? Perhaps that's too cynical, I don't know.I am convinced by now that recruiting Wikipedia editors by offering a workshop nearby is a terribly ineffective measure. We always easily get funding for such initiatives, and we might do them for the publicity. But to increase our editor base there is hardly any method less successful than running workshops.
