Anyhooooo - if all us pool miners set our payout trigger to the minimum will that increase the number of Bitcoin transactions, and therefore increase the number of blocks being processed and therefore ultimately increase the reward we get for mining!!!!!!!
It wouldn't increase the number of blocks being processed, but more transactions per block could increase the fees per block, ultimately increasing your share of each block by a small amount. Fees per block are minimal right now that it wouldn't make a huge difference.
