No, not at all. I cite non-academic sources (light table, Bret Victor) all the time in my research, however keep in mind: you are writing for your readers, and you understand their mindset. Writing for an ICFP crowd would be a bit different than writing for a hackernews crowd, so you would compare against more academic work (especially since the program committee are academics) and not so much industry projects.

A 12 page paper can never really be "complete," so optimize for the intended readership.
