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 :)
Could not agree more with cookiestack. The inspiration is quite clear and not giving any credit to what influenced your work is somewhat surprising. Especially given the fact that this is supposed to be a job application.
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/).
