Hey David,

I really like what you have done, a nice twist on the ol' like button. And its a pretty cool looking site as well.

One thing does, well, concern me a bit, and its that you haven't given credit where credit is due (http://jeffkreeftmeijer.com/2010/experimenting-with-node-js/).

There is no doubt that this is very similar to Jeffs blog post, and although it takes the idea a step further, I do think you should at least add a link to any and all code which inspired you and which you took ideas from, if it be Jeffs previous post, or a Node Knockout project.

Best of luck with getting Valves attention, and you have my pointers vote :)
