I think, yes, for content oriented sites (seo benefit, helps to allow people to continue to view content, etc), but if it's an app/utility site, I think there is no point in adding to your workload...
I would assume for a content oriented site the most optimal development path would be a CMS as opposed to custom development. Something like Drupal or Wordpress is going to give you a significant time to market advantage over developing a site in either a server side or client side framework.
In this case, it is an app site. I was sorting thinking along the same idea.
