I agree with the factual errors that some pointed out, btw. E.g. the suggestion that any well-respected cryptographer (i.e. one that has published articles in the past two years in well-known journals) has looked at Bitcoin seriously is a complete lie.
As for the scientific progress concerned, Bitcoin is still at the experimentation phase, I'd say. I don't really see why the main author doesn't submit a journal article somewhere, as writing such an article is pretty easy, if you know what you are talking about. Figuring out what to write usually takes a lot of time, but writing down your research should be easy.
