Just wanted to comment here, since our Smash Balloon Instagram and FB feed plugins are already used by over 1.2 million users, we have added the oEmbed functionality to it.

This was easy for us to do because to create custom feeds, users would have to use the API key anyways. Over the years, our plugin has simplified that process to make it very user friendly.

I think it’d be helpful to recommend these because we DO NOT require users to go through a complicated FB app setup process.
