I'm over 30, but I'm tech stupid compared to everyone else here, but I can follow, and understand the jist ftmp of the conversation. Not my area of expertise. I grown up with the internet though obviously so I do know my way around.
If anything i'm probably just more open to new experiences than the average person, and I like learning stuff.
But in general I agree with your observations, and it seems natural for early adopters of a platform.
