Superb initiative, thank you!
A feature I would really like to see is community admins being able to set recommended or mandatory payout percentages (anywhere between 0.1% and 100%) that go to a dedicated community account. So that posting in a community and earning rewards there becomes a fundraising initiative for the entire community. The community then can have its own governance mechanism for how the funds are used (presumably it will be to further the community's purpose).
Another feature is advertising in the community, with the ad revenue going to the community-dedicated account. If I understand correctly, @imwatsi's Native Ads Protocol will make this possible.
Yes @borislavzlatanov Native Ads aims to make that and more possible :)
