[ksk-rollover] Gathering operators' voice

Following is what I said during KSK Future BoF today. To gather operators' voice widely, conducting survey is a way. Operators are shy to express their experiences to the public mailing list, but they can answer anonymous survey, and then surveyer can proxy their answers anonymily. We can do it in our local community in local language, and bring it back to this mailing list. -- Yoshiro YONEYA
