" Without a healthy and diverse community of participants, the quality of our content will suffer."
Sorry, should have clarified that the statement was purely subjective personal experience - and back in the 90's at that. I volunteered with Project Gutenberg for several years working on editing previously scanned in documents. The culture there was not combative or male-orientated in my (obviously limited) experience... but whether that was reflected in gender-diversity or any other kind of diversity I couldn't say - though I'll see if I can track down any stats. On Wikipedia I'm very aware of my gender - and my English reserved nationality! - in a way that didn't seem to be at all relevant there. I'd guess that the delayed publishing and hierarchy in editorial process helped with that. Things that probably couldn't be applied to Wiki - although the editors with admin privilleges go some way towards that and I'd personally like to see more of them around to create more leadership within the community. There may be other ways in which Gutenberg manage their volunteers that might provide useful pointers. If you're interested I'll go see what I can dredge up.
