When I first joined, I tried to recruit some men of the relevant age at a hobby group of which I was a member. These men were there as much for the craic as the hobby, and would sit and chat about what they had been doing, and spoke of their families and mutual friends too, so I thought they might be interested in a social network for people over 50.
I described Gransnet - conversations about politics, religion, homes, TV, painting, photography, etc etc - "and of course families and grandchildren." Result - zero enthusiasm and a degree of embarrassment that I should think they might like it. One even said "I don't want to listen to a lot of women boasting about their grandchildren!"
When that is their image of women talking together, even when they have been told of the wide variety of subjects discussed, there is very little hope of men wanting to join a network where ANY women might be there and might just mention children. When men no longer believe that women are only interested in fashion, children and knitting, they may condescend to speak to them .
Until then, no point changing Gransnet to accommodate them - if they want to join they are always welcome. Which is more than could be said when women wanted to join men in equal discussion.
