My Wikipedia update to the virtual box page here: http://en.wikipedia.org/wiki/Virtual_box was removed within a week of me updating it. I think there are many factors for why this is. First it was my first edit under that username so as a new user my edits could easily come under scrutiny. Second the sentence I posted wasn't entirely true. I said that virtual box now supports Chrome OS, but it technically doesn't officially support it, it just happens to work with the developer version of Chrome OS. So as I thought before, and this only reinforces my argument, that wikipedia isn't perfect, but I don't think it ever tried to be.
