I found https://soapbox.wistia.com/ and I think I'm gonna try to make a whole series of videos like https://blog.prefab.cloud/blog/feature-flags-for-ruby-on-rails-in-6-minutes-with-manifold to help me explain Prefab.Cloud. Somehow video is easier to produce than trying to wordsmith a blog post.
I'm curious whether people like watching videos. Myself I often don't like videos because I don't have headphones in, but I have a feeling I'm a minority opinion here.
