This video, compelling as it is, has been around for a long time, And as you say, it tells us what but not how. Your points get closer to the how, and while they, too, are variations on stuff being said, they're clear, useful, inspirational, and all in the same place at the same time. Will have to bookmark this one.

It seems it might be ok to automate news updates, product updates of information that a brand knows a customer or follower would actually want. But it won't work in terms of any real dialogue or exchange of ideas. More importantly, it's impossible to be be truly authentic, honest and transparent simply issuing automated content or attempting to provide automatic responses. In fact, without real exchange and human interaction, it will be impossible to know what it is an audience might actually want from a brand, which is what would have to inform the automated content to begin with.
