Hello 
Just want to present a new tool built on top of Middleman.
Tonic
Tonic parses your collection, defined in a YAML or JSON file, and automatically generates a customizable static website to explore your collection in a smart way, with a lot of filtering and sorting options.
Feel free to share your feedback!
This is pretty cool. What do you think some good applications of how to use it would be?
Thanks @donnfelker! Much appreciated!
Initially, I started to build Tonic to (eventually 
) re-write the Awesome Ruby website (https://awesome-ruby.com) and make it more explorable, including data like: downloads, stars, authors, last release, … It would be really useful! This can be extended to any awesome-* like collection.
But you can also build a small online shop, using for example, links to Stripe for the checkout part in the detail page of each item.
Another ideas:
Do you have any other ideas in mind? Any kind of structured data can be displayed and explored by a Tonic instance 
Also, it seems this could be of interest to some librarians/archivists.

Thank you for creating this. Looking forward to exploring the source code and learning 
Glad you like it!
Next week I’ll release a new cool feature: allow to filter by parameters
