If you want to upload your thought on the internet and don’t wanna mess around with it that much, then I can recommend neocities.org. This site usually hosts personal websites, and there are a lot of sites which offers website template. You just create your instance/domain/site on neocities, choose a template and paste that code in. After that you can just paste your notes into the <p> tags and you’re done basically!

My philosophy is to just focus on 1 or few communities, instead of having a bunch of communities which will lack (more) content, but I hope it works out for you. Well gametheorists has grabbed my attention ngl. ^^
