Why mine at any other pool when Eligius is 0% Fees?
Downtime.
I guess you could do elig + a backup pool.
Not sure I've experienced any downtime in the past month or so that was caused by eligius.
And please tell me, why do you mine at Eligius? Such an ugly site! That Wizkid and his pool.
I mine at eligius because with 11 Jupiters, 3% Fees would have been over 11 Coins already for me that I would have given to BTCGuild or other pools.
Why mine at any other pool when Eligius is 0% Fees? Because you like pretty Stats? Not worth all that lost money.
Also 105% PPS NMC helps out, get an extra coin or two per month. Pool basically pays you to mine there
Ghash.io has 0% fee, pays transactions to miners, and merge-mines NMC, IXC, and DVC - and their stats page seems to be very reliable.
Ghash.io has made it extremely clear that their fee is "currently" 0% and could likely change it in the future. They are directly connected to CEX.io and have the majority of the networks hashrate currently.
Unless Eligius gets too big I don't plan on switching and would sway others from joining a pool that currently has 24% of the network https://blockchain.info/pools?timespan=24hrs
