I see that three pools are stickied in the mining pool section, slush, db and btcg. What is the reasoning behind this apart from the fact that they are the three biggest pools? Given the way the system works, should there not be a drive to diversify the pool usage instead of push the big dogs, who either have a fee or really really ask you to "donate?

What is the policy on which pools are taken and, given the real profits pool operators make, is there any financial sponsorship involved?

I think there should be a strict policy in regard to sticky posts in "business related" areas that do not promote products but only free and unpolitical elements and if anything should be stickied there, it should be the "proven to be reliable 0% fee pools" and not the big racketeering pools.
