There's now a read-only demo of Epochtalk operating on live bitcointalk.org data which you can check out:
https://demo.epochtalk.com

Right now only boards, topics and user-pages are supported, and it's read-only, but over time I'd like this to become an increasingly-useful alternate interface to bitcointalk.org. (Only when it's feature-complete and bug-free would bitcointalk.org switch to Epochtalk.) Already, some people might like to use the demo on mobile devices, where it often works better than the current site. Also, if you look at the requests that the site makes, you can see that it has a JSON API; people who run bots might like to check that out, though we don't officially support/recommend relying on this API yet.

If you see any bugs, use the "Report a bug" link in the top right of the demo.
