If Microsoft wants developers to develop for Silverlight so bad why don't they just make a Chrome OS plug-in? The thing is open source. Moonlight already runs on Linux. Wouldn't take a rocket scientist. That's even if Google wants Silverlight to not work. They clearly support Flash and I suspect they want the Chrome OS to support the entire web including Silverlight sites. So now you have open apps working on Windows and Silverlight apps working on Chrome while Robert Scoble just seems kind of stupid.
