I'm wondering about some technical questions of this and maybe figured out a solution to it.
Others who receive the posting key will be able to post and edit comments/posts of anyone and everyone in the past. The only way I can think of this working out is if the posting key keeps getting changed for every participant who's turn is to do an AMA.
Why not just post like other accounts projects, gain a following and re-steem other AMA's? Are you a new member or an existing Steemian? Where is the safety that you won't just go quite at one point and start powering down into an exchange?
@acidyo thanks for the questions. You are right that the keys would be shared amongst participates. I guess this account is really for the non-steemian, so to speak. I'm still working out how to handle the keys aspect.
@steemitqa is me running this :)
Ahh okay lol, you hadn't mentioned it at all :D
