In my age survey thread on another photo forum, someone commented that the lack of younger participants (under 20) waa due largely to that demographic group not liking to use formal internet forums - that they much preferred a more interactive, spontaneous, "push" style such as Instagram. The participation format of sites like this doesn't appeal to them. That's the theory (*).
Women have always been scarce in any of the forums I've participated in, Firearms, Mechanical Watches, Sports Cars, Photography, and Music (sax and guitars). There's one exception: a site devoted to professional language translation. There, women seem to be a majority.
It must be you 🙂
In over 30 years, no woman has noticed my M3, M6, Barnack Leica, nor any other camera I have. Actually, nobody has.
(*) A similar observation was made years ago in one of my car clubs: younger people aren't inclined to the formal "meet at this cafe the first Tuesday of every month" style of club. Rather, they are loosely-knit and communicate and arrange drives spontaneously by text messages.
