Microsoft has updated its Microsoft Answers site with a new look and feel, a new reputation model, and other new features. It's worth checking out.
And finally, while I'm still working to complete Prestige 15 in Call of Duty: Black Ops, what looks like a teaser site for Call of Duty: Modern Warfare 3 has gone live. There's nothing to see, yet. But ETA is November 2011. So I guess you could just leave that page up until then. It will never get annoying.
