Where is everyone?

[AsDaRa]

....and, of course, the very idea of message boards/forums does not appeal to younger people who prefer the instant self-gratification of Facebook, Twitter, Snapchat, Instagram, and a host of other things I've haven't even heard of

But you need to know these people. In a forum you can ask a question to the world, in your Facebook to your friends only.
A forum can not be compared to social media. The younger generation will also have demands which only a forum can fullfill.

Say you want to know which dildo is best, you will ask that in Facebook for everyone to read (including family)? No, you will ask it in a forum under an anonymous name. Forums fulfill a need, also for the younger generation.
