Such a DAC might be good, but we should not over complicate things and excuse our doing something simple by staring into a complex optimal solution.For certain bounties, we get the tech gurus to judge, for others we get a few members of the community to judge, for others we might hardly need judging, etc. This is the cyberpunk solution, but we know from other communities that it can be used to great effect, so the possibility of an optimal, or even just better solution, should not weigh us down from doing what we can now.
We could just put up a poll on this forum if we decide to do monthly awards, for instance:
Most inspirational post of the month,
Most helpful member of the month,
Best constructive feedback of the month,
Awards could be PTS from the bounty pool,
donations from community members,
gifts from I3,
being featured on a section of the bitshares page,
One recent thought I had is that it is important to highlight users,
show appreciation for their contribution,
and give their reputation a memory in the system.
