It brought me back to a time when I used to work a lot with developers and one of the acid tests for someone who had coded an extremely complicated bit of software was ”can you eloquently explain what it does in 30 seconds or less, so that anybody can understand it, including your grandma?”

I have the same experiences in project development when people seek funding at my job to address a regulatory concern. Attracting attention requires an elevator pitch whether your buying kitchenware or refueling a nuclear reactor. You brought up a good point I've ignored, unfortunately, regardless of a defensive reason.

So, then, I guess my 30-second (20-30 seconds) explanation would be this:

Start of pitch
Verify Your Brain (VYB) is a new tribe that allows for content creators, of any niche, to share their content and opinions with others. It proposes a moderation mechanism centered on justification, verification, and communication. It is also intent on allowing members the opportunity to expand this tribe following community review and approval.
End of pitch

My desire to support this tribe comes from a belief that a tribe owner is just that...an owner. For a community to be successful, it is their responsibility to drive it forward. That responsibility doesn't solely lay in the owner's hands.
