I think I may have spent so much time listening to Rosenstein that I ended up not knowing anything by the end of the video. There were far too many tech-hipster soundbytes which obscured the real value of the product. Thankfully I was able to read up on it at a few other sources, and watch the live demo bits with the sound off and get a better picture. Overall it looks like a useful app, which offers a few of the things that I'd like to see in Jira.
