you talking free? It also depends on what you're using it for. If it's just a blog, you have a few choices like WP, Drupal, Joomla or you can try Moveable Type.

You should check the plugins marketplace for each platform to check about RoR integration.

Look for something called an LMS. There are SaaS providers, open sourced, licensed and selfmade ones.

LMS = Learning Management Platform

Thank you, I had no idea this term existed. A simple search brought up a number of options like Moodle and ATutor.

Ok, so I'm looking/reading this article basically saying that this new version of an instagram-like platform is going to replace it and it's on a subscription model. Ok, I get it, this is a good way to monetize, but in the grand scheme of things, no one wants to pay for the convenience of no ads..well, I don't. Maybe it's because I'm cheap. 8-)

To me, what Vimeo is to Youtube is what Vero is to Instagram.

Would you pay for a service like this? Would you pay for ANY social media access? It's bad enough we have to pay for tools to manage social media let along the platforms themselves.
