I totally agree, and it's great to hear the backstory of your process, which is typical of so many companies that start with Ruby/RoR and then grow (e.g., Twitter, Github). Here's a question that others might value for you: Would you have written the app originally in a different language(s) or framework(s)? Or is the approach you chose (start with Ruby then selectively refactor), the approach you still would have taken given all you know now?
