For Star Trek, not so much. After one TV episode, you might not know a Tribble from a Romulan, but you’ve probably figured out the whole Vulcan thing. Much more approachable, much easier to fake your fanhood

Which is why fans themselves create, determine and police levels of “insider”ness. This is what fandom IS! (Well partly). It’s not a case of ‘choosing’ approachability or depth: having fans means delegating that choice.
