I decided that that wasn't very user friendly. It doesn't tell people what it is. Or how to use it. It doesn't explain any of the concepts or vocabulary.
So I asked it to add those things, above the main interface, including the steps people need to take to use it. I think it did great, and I think the small text sizes with a clear title let people who need it, read it, and people who don't can just scroll down. Even with the text it's 600 words.
I like the effect of what it's done. It's better than I would have done if I had written those intro words myself.
Clearly it resonates with people, this thing has been on the front page of HN for 4 hours and with 110 points is by far the most popular thing I've ever posted here.
