This Saturday at 10am EST (1500 UTC) I'm hosting the Steem Witness Forum. 
Multiple Top 20 witnesses have agreed to come on air. We'll see what the final count looks like, but so far yabapmatt, followbtcnews, and a few others are tentative.
We have a few backup witnesses that have asked to come on.
Show Format
Steemit typically comes on first and provides us with some perspective of what they have going on. After 30-45 minutes they stay on the call if they choose, but it's witnesses that lead the discussion. If you have questions you'd like to ask Steemit please leave comments below and I'll try to incorporate them.
After Steemit has gone I try to ask open ended questions, usually informed by the previous discussion, of what different witnesses think is the right direction for the platform. I give prompts and they're given a chance to answer.
