BitMinter has been zero fee for a long time. Unfortunately this is not a sustainable way to run a pool because most miners set their donation to 0%.
I've been mining on bitminter for several months now and I can't recommend it enough - okay sometimes the pool gets unlucky but sometimes it's also really lucky - it all balances out. With a lot of new hashpower coming online, the variance is also the lowest it's been. Out of all the shares I've submitted I just calculated that my stale/reject rate is 0.076% which is pretty good.
Thanks to DrHaribo for maintaining the pool.
