This looks pretty cool! It feels like a new take on the idea of mailing lists. One suggestion that came to my mind, is to have the ability for viewers to subscribe to conversations. It could be either through Email notifications or RSS.
Fantastic suggestions, thanks – we have a notifications system on our road map but are still formulating the exact mechanics. We would also love to support RSS! One of many things that we will try to get to soon.
If we're making technology requests, is it too late to ask that the site work without JavaScript? I guess you could say "It works without JavaScript because you can interact via email", which is fair, but if you're adding support for RSS then it would be nice to be able to access the site via an API or with curl.
