Ebook Marketing is a key way to simply build a quick fortune...

Or so I've been told.
Of course my own methods of study are to grab all the freely-available PDF's I can and then extract the useful data from these in order to make my own conclusions. (And you'll see my own ebook on this shortly, BTW).
And in that, you get actual examples of well-executed ebooks and what comes across as pure amateur.
The point is that this is one industry which hasn't reached saturation yet, so the early adopters are making tons of money and becoming million-seller authors within a few years if they work it right.
