&gt; Rails remains to this day the tool I go to for building web applications because it&#x27;s so well suited for building something quickly. Sure the effort to make it scale is present but I see any scaling effort as big regardless of framework or language.<p>This is why I continue to use Rails despite being interested in this that and the other new thing.  It&#x27;s very productive in terms of getting something up and running.<p>I mean, heck, Twitter started with Rails, and despite some hiccups, managed to grow.  And Twitter is pretty much the poster child for something that has to scale massively.  Odds are, you won&#x27;t have the same problem.
