Interesting, I was under the impression that Women was the bigger group.
To be honest, IMHO Information has no sex, so to me is kind of worthless info on what gender post more than other.
What I will truly encourage is for more accurate info.
Wikipedia is not an 100% trustworthy site but is pretty darn close to the reality.
Most of the ranting and bashing when you go to comments, is more about grammar on what kind of writing style is used.
And that is subjective.
I edited posts on the Wikipedia before, even as a test, posted some bogus info to see if people are really watching. To my surprise, someone already fixed some that I changed the way it was before. Also, depends on which topic are you messing with and hit counts.
They should encourage more people to write honestly than bringing more of one kind of people.
