An interesting look at an interesting proposition. Clearly, though, examined from the perspective of an "investor", and a skeptical one at that. Nevertheless, and if one bears that in mind, the piece has its moments. The amount of detail is commendable as are the historical reference points. As a minor quibble, the Author does elide a bit of information in regard to the aforementioned, however this does not detract from the overall interesting nature of the write-up. All in all a generally worthwhile read on a lazy Summer Sunday if for no other reason than the diversionary aspect.
