I honestly prefer AMA's over even things like whitepapers i just find them to answer directly a lot more of the questions that actually matter while papers tend to have a lot of stuff that i could case less about, while ama's allow people to target the things that matter to the investors
Yes project's whitepapers are very technical and sometimes contain too much information for the average Joe (myself included) AMAs get to the point and it is useful for community members to find out information about their favourite projects. Neuroneum should think about running one soon.
