What Does It Mean to be a "Seed" or "Seed Person" of a BUD?

A:

A "Seed" or "Seed Person" is one of two things or possibly both:

  1. They are the founder of the BUD
  2. They are the spokesperson and point of contact for that BUD

Not everyone who creates or founds a BUD is outgoing or likes to speak in public settings therefore the BUD might select someone other than the founder of the group to act as a spokesperson or point of contact  for them.
