It's too early to get a clear picture, but my thoughts so far:

First, most people complaining about merit are constantly posting garbage, and should not rank-up. The forum is not a welfare system; you don't run through a few hoops and then get paid for doing something that nobody actually wants. I like that good forum members can make money, especially when said forum members are in poorer countries and this is a major opportunity for them. I very much do not want to destroy the sig-ad/airdrop/bounty "industry". But I am not going to tolerate people posting garbage upon garbage. If the merit system completely fails and I can't think of anything else to replace it, then my next step will probably be to completely remove all ways for forum users to make money from posting (eg. removing signatures entirely).
