[Kumabjorn]

At the risk of outing myself as a major nutcase I have to confess that I sometimes have conversations with the author in my head. Especially when I encounter something that is simply wrong, misunderstood, misinterpreted, misguidedly erratic, woefully invalid or sometimes simply bumptiously preposterous. I find myself urging the author to correct his mistakes and wooing her to publish an updated revision. That got me thinking - fearful impression as it may be - that if that happens with a printed item it is fairly easy to look it up on the inside front pages, but alas, I have no way, at least not to my feeble knowledge, to know what edition I'm offered when the book is electronically published.

So I'm wondering should we get an updated revision pushed to us automatically? For free, or offered at a discount?
