I understand the benefit of recurring supporters and of maintaining in the public conscience the reminder that this is a publicly funded resource of the commons. There is no excuse though, to pleading for money in a way that suggests dire straits. What if an organization made a deal with people, to get them subscribed for something like $2 a year with a 'burst' up to the cap set by the user that triggers at some funding floor? $2/year until our endowment goes down to $30 million, then $10/year until it gets above $50 million.
