I haven't been able to play with it too much yet, but I liked what I've seen. The interface is very clean and well done for a launch version.<p>I typically like to do more and more things in a terminal rather than in a GUI or web interface, especially for that kind of things, but there's definitely benefits in having all requests logged and easily accessible and editable.<p>Some aspects look like a very nerdy version of a social network (stream, share, favorite), which is kind of surprising but I could see how that would be useful sometimes. I have a backburner project using the Heroku API (which I've found acting weird sometimes) and that should be a good way to test it more.
