Re: Small time miners - What do you do when ASICs hit and you don't upgrade?
well if you mine for fun then you want to see some BTC coming in dont you? so why not picking the pool with the most payout 
If my ASIC pre-order never ships and others ship, I may point my GPUs to p2pool. But if it arrives, then I will probably take out my GPUs and put the nVidia one back in.
I don't think I would point my ASIC at p2pool since I haven't really studied the effects of increasing your own difficulty for the benefit of the smaller guys in the pool.
