Hi Beau,
I decided it was better to push my images to Instagram instead of pulling them from Instagram. Why? I like displaying the EXIF and IPTC data from my images. Instagram strips that information from the images.

I have read (and re-read) the documentation for Keyring and Keyring Social Importers and I am poking around the code. I am hoping I can write an importer for Untappd. Currently, I am using Zapier to push my Untappd check-ins back to my blog. It works but I think Keyring Social Importers offers a better (and more controllable) path.
