Does anyone think giving out more sMerits per good post would help? If I'm not mistaken, merit sources get topped up pretty quickly so giving out 5-7 merits for a good post shouldn't put much of a ding in their supply.
I think a better idea would be to create more merit sources and thereby keep the system as decentralized as possible, but as theymos seems uninterested in adding new sources, this is maybe the best idea in the meantime.
5-7 in place of 1 seems excessive, however. Perhaps the sources who regularly have lots of merit left at the end of a month should just double how much they would have given.
