Even if every point the author makes is true - there are still plenty of reasons why you should use rails in many cases. The first of which I'd argue is you can get shit done fast! For startup founders, this is essential. Make something. Put it in front of users as fast as possible. See what they like and dislike. Fix it. Repeat. Rails makes this super fast and easy. Once you get to the point where you really care about any of the things this guy mentions, hire a team to rewrite it. You'll need to at some point anyway...
