Thanks for taking a thoughtful approach to your future operations.
What chain do you prefer us to operate on?
Hive I guess. It is going to need some familiar apps to help it gain traction.
What do you like about Hive?
Its potential, and at this point that is all anyone can truthfully say.
If you want to stay on SteemPeak.com tell us why.
I am a new user of your service, so again I like its potential.
What 2 URL choices do you prefer for our re-brand?
Based upon your vision as outlined of what you hope to become then PeakSocial.com is the most promising. The other options listed seem contrived and gimmicky that will not age well.
What chain would you prefer our witness to be on?
First of all, I don't like the term "Witness" for the functions that one performs. A better generic term would be "Advocate". But to answer your question directly; if Hive is your home base then on Hive you should advocate for the community.
