Not only that, but we also need to take into consideration the important factor that as bitcoin grows in price, so does Bitcointalk's traffic, and most probably so does ChipMixer's traffic(hence also an increase in earnings). So I guess we can probably make the assumption that it sort of all balances out in the end?
I admire your optimism but I don't think $30 per post will last... doesn't make much business sense when everyone would happily participate even with a 90% reduction.
