I've been disappointed by the lack of online communities dedicated to people who are interested in the craft of drafting constitutions.
One of my pet-projects is to work on a draft constitution for my country (i.e., Taiwan) in Google Doc, which has a reasonable chance of rewriting its constitution within my lifetime. The level of research and creativity that goes into it is profoundly stimulating and enjoyable, it calls on all of your intellectual faculties in law, humanity, ethics, etc.
I just want to find a place where I can talk about these things with like-minded people and perhaps swap our projects. I've tried Reddit with little result.
Hope that I'm not alone in this. They did say no interest is too niche on the Internet.
