So critical mass is defined as the moment when community members are responsible for 50-90% of the organic growth and activity.
My community is a product - thats how we define it anyway. Members have to buy a continuity subscription (ie, they pay month to month for access to trainings) and the community is positioned as a free bonus to their paid membership.
How can critical mass be reached in this case if members cannot organically invite other members to the group? It would be more like they invite them to purchase the membership, which totally happens all the time.
Say we set up a referral program for members to invite others, with the incentive that they get discounts on our trainings. Would that count as WOM and reaching critical mass, even though its for the membership AND the community?
Hope that makes sense...
