I think AMA's should be closed for comments after a while because the op may not be around to respond to a new question for example 18 hours after an AMA, but it's still on the Frontpage and a new question left unanswered can be a bad look even tho op might have had an answer

I also think we should be given a heads up and be able check out a project and maybe ask questions some time in advance it may lead to more engagement but I could be wrong
