Thus far, the experiment has been fantastic. I've written a considerable amount (about 2,000 words in two sessions) and have decided to open up the comments feature so people can ask me questions while I'm writing. In other words, I'm loving it.
For anyone interested in watching me work, or seeing my progress on your own time, all you have to do is go to this link. I will announce live-writing sessions on my Twitter and Google+ pages. And if you show up during one of those sessions, feel free to leave a comment with a question!
