Linen product looks very interesting, but I am not sure about the cost of running Linen. In particular I worried about cost per user - 50 USD for 5000 users. Usually, with time communities accumulate inactive users. It is quite possible for a community to have 100.000 registered users from which only 1000 are active the rest 99.000 users do not visit community at all, but by the current pricing model the community owner should pay 1000 USD per month. Most of community building platforms charge per usage - monthly page views (e.g. https://www.discourse.org/pricing). Will it be possible to make pricing based on the usage?
