Look - I'm am the opposite of DHH fan -- that said -- they could fix all these bugs/security issues that same way they created them. It makes sense to some extent to create a product that emphasized what is different about it from a feature/UX perspective so people can consider if it would even be useful to them at all. If they can prove that they have created something useful - then they can fix all these issues. Fixing these issues is not hard. Creating a useful product that people want -- this is the hard part.
