I would be more impressed if Discourse worked in my browser without using an extension to inject code changes. It also tries to forbid browsers it doesn’t recognize, regardless of their ability to run its code. Plus it doesn’t downgrade gracefully—you should be able to view public information in full without Javascript (I don’t expect any ability to log in or manipulate content, but reading things should work, and Discourse seems to break scrolling somehow). Not impressed. Granted, I’m not sure what I would choose if I were setting up a Web forum today, since mobile is now such a Big Thing and I don’t use it, but Discourse fails at things I consider basic.
