Looks cool, not sure if it's working 100%. It prompts me to 'Type post number to open' but when I do, It just gives me the same prompt until I type 0 to exit.
It should open up the URL in a browser when you choose a post, it looks like the 'open' command which I'm using is Mac only. What platform are you on? I'll look into fixing it.
Thanks man! I've pushed a new version to npm that should have support for Linux and Windows now. I've tested in Ubuntu but let me know if you have any more issues.
