[OSGeo-Women] statistics on Google MapMaker and Wikimapia

[Renate Steinmann]

Hallo all!

Currently I work on a research project which deals with Volunteered 
Geographic Information (VGI). My question now is: Does somebody of you 
have information on demographic user data (Age, education etc.) of 
Google MapMaker, Wikimapia, Geograph and Panoramio?
Can you help me, please?

Yours,
Renate
