I like it when people are actively thinking about the what/where/how of stuff. Sometimes not enough of this is evident.

As for who those under-represented folk are - people quietly getting on with it I guess. Maybe those that interact more in other forums, or who like to keep themselves to themselves. I know a lot of people who just enjoy playing with 3d but don't really produce renders they want to put up for public consumption for one reason or another.
I have numerous accounts for sites where I might buy items from a marketplace but rarely if ever visit the forums,
