While it's true that some improvement need to continue to be made for bitcoin to become more practical for most people in day to day shopping/living situations this author comment about bitcoin potentially being a trojan horse created by a cyber criminal who's going to make it all crash down at the right moment is really amazing to hear. I wish people would do some more research before making such comment in such a widely seen blog post.
If you want to contact him directly and explain why the technical aspects of bitcoin or safe or how the core developers of bitcoin are known to the public and we can all see whats being worked on and put our input feel free to let him know at
williams@bu.edu . Jut keep it polite and respectful, I think a guy like this would probably change his mind on some of the comments he made if people politely let him know what was wrong with what he said .
