I wonder if this could be remedied by using a front end Web App Server consuming the JSON API. So you would have a JSON API server and a front end Web App say in Node using the API as a database. You would have the advantages of building a SOA architecture, letting the API server do the heavy lifting. And you could reuse a well tested API for Mobile Apps. I would think a Meteor.JS like front end would be an ideal solution for low traffic websites(Not twitter!)
