Not to nitpick, but "[...] running C code in your browser" is a little bit of an exaggeration as there is no state-sharing between cells. It's similar to a webpage that posts C code to a web service and returns the output of its stdout (so like CGI). Not that this is a bad thing, but when I read about stuff running in the browser, I suppose the code to be run by the browser itself, and not just visualizing the output of a program run on some remote server.
