Hi Everyone,
I thought this might be interesting to the general Rails community.
Cloudant did a write up on our product
Classroom 7. The product runs on Rails, Backbone.js and uses Couchdb as its main data store. More details in the article.
https://cloudant.com/blog/classroom-7-bootstraps-online-learning-site-using-cloudant/ Also the latest version of Couchdb (1.5) is about to be released which includes a completely new single page application frontend written in Backbone.js. I am part of the open source team that developed it. You gotta check it out, it looks great and we used some pretty cool javascript to pull off some of the features we wanted to do.
Let me know if you have any questions.
Cheers
Garren
