One might presume the appropriate metric to be reported hash rate. But if that's the case, why are:
[40 GH/s] Ars Technica community mining pool
[62 GH/sec] MineCo.in - LP,EU Server,SSL,JSON API,0% TAX
[115 GH/s] BitClockers.com - Secure/Google Auth/API/US+EU/InstaPay/Live Support
granted the sticky placement, when bitcoinpool, currently around 175 GH/s, is not?
