No, I want the pool to be 100% stable. It's plenty big enough to work now, adding tons of little miners who don't have 50MH each just causes a lot of server traffic.
As the owner of a brick-and-mortar company that does work for businesses, as opposed to individuals, and mostly decent-sized corporations, there is something to this big miner vs small miner thing.
If I were to start a pool, honestly, I'd probably design it to attract larger miners (10MH+) and discourage smaller ones. Providing support to a small number of large customers is SO much easier and more lucrative than a ton of small ones.
Easier? Hell yeah, definately. More risky? Also.
As the owner of an hostingcompany with tens of thousands individual customers (and also SOME large corps), we've had little or no problem with the recession/crisis/economic meltdown. Instead, we've grown almost twice the size in the last few years.
My point being: when you dedicate yourself to a small pool of large hashrates and get a lot of issues as middlecoin has right now, you wouldn't lose 1 or 2 GH/s as it did in the last few days, but you'd lose a lot more then that. Just as it wouldn't heart our profits too much when we get a big interruption of our services due to lets say... a DDoS attack. Better for the long term in my opinion, but I would understand when you disagree.
I switched to wafflepool yesterday and get 0,02% rejects. Don't know yet if it is the same or more profitable, but I'm gonna try it out for a couple of days.
