Let's be objective here.

zpool has 2% fee, 180+ coins, running for 2 years
hashrefinery has 1.25% fee, 50+ coins, running for 0.5 year
ahashpool has 1% fee, 70+ coins, running for 0.5 year

Yet, pinpins is new to running a pool, says he is a 1 person team, decides to charge 0% fee, and add 160+ coins.

If you have 160+ coins in zergpool, you better make sure you are in contact with 160+ dev teams and git repos and monitor 160+ coins on a daily basis to prevent chain splits and forks, and handle upgrades in a timely manner.  Don't you think this is too aggressively to the point of recklessness?  And you think a new pool admin is able to handle 160+ coins better than hashrefinery, better than ahash, to the point as good as crackfoo who's been doing it for zpool for 2 years?  I'm just pointing out the numbers.  Maybe pinpins is super human, who knows!
