Ah, bummers. I know this was your baby, and you put so much into it. It's certainly sad to see it go, but you do have to set and maintain priorities in order to stay as effective as you have been. You are a productive machine!
I hope someone else sees the value in this technology and takes it upon themselves to run with it. I wasn't personally a big fan of the forum style comment threading (too many lost days in bitcointalk, I guess), but I loved supporting and promoting ChainBB because I believed in the work you were doing and thought it was an excellent example of what's possible with the STEEM blockchain beyond just Steemit.
I'm sad to see it go, but proud of you for making a tough decision.
