Not related to the language switch, but I just want to say that I love Asciinema. Thanks to it I do small screencasts where normally I would be totally discouraged about the amount of work needed in order to really record a portion of the screen and upload a video recording. For people that want to show most of the times terminal based things (i.e. programmers), it is a zero-friction way to show an interactive session. Thanks for building it.
I actually discovered it from your post the other day, antirez. The CLI thingy. And I concur. It is a truly wonderful tool I will be using extensively: Docker inits, first N steps in spinning up an instance, setup devenv and build first "hello world," and much more ;)
I'm not so fond of the fact that recordings are served through ascinema.org. There are alternatives like ttyrec + tty-player that work just as well and don't depend on external servers.
