The bulk of the sites I've worked on at NFP were templated using Liquid.
I use Liquid a lot in my current role at NFP because that's the main way to re-use content in our CMS, which is DNN Evoq. I also got a Shopify subscription and transferred my Coat & Tails site there. So I've used both versions.
Disclaimer: Many, if not all, of the sites listed here were and continue to be a team effort. Design, content, and development choices were not and are not exclusively mine, and I may or may not be exclusively responsible for the maintenance. That said, I had a large hand in the development of all sites listed here, and, at the time of this writing, am generally pleased with the result.
