First of all, congratulations on what seems to be a very well executed rewrite.<p>That being said, it will be interesting to see how this compares to all the stories about dangers of rewriting. I definitely want to see an update in a few months about the results.
Awesome! It's nice to read accounts like this from those who have braved the task and successfully completed a ground-up rewrite.<p>Looking ahead, I can see the formation of dedicated development teams who specialize in rewriting working-but-just-barely apps completely from scratch. As those teams get better at doing this kind of work (and their clients prosper!), more companies will start to seriously consider the re-write option. Who knows, a whole industry could form just for app rewrites.
