I believe that, with the economy in the way it is, it would be beneficial towards the health and longevity of Second Life for Linden Labs to offer discounted incentives for private regions who run not-for-profit communities on this game, much like educational Institutions and charitable institutions are able to do. These should be regions that do not monetize or commercialize their estates, and also not be a private region (family/personal residence). They must have a focus on a community/project. This would be a great incentive to bring back exploration sims, more roleplay regions, combat/game sims, as the price of these regions is large and entirely unforgiving towards people's passions. Especially with how the economy is right now. To apply to this, the project would need to be pitched to a team to ensure the project does not encroach upon IP and would meet the standards needed for the discount to be approved. I have seen many sims vanish due to a lack of sufficient funding, and this would help in the long run of things. There would likely need to be rules on store vendors, rentals, and donations, but that is manageable.
