According to The New York Times, Microsoft will soon be advertising within Facebook. Perhaps this is because Microsoft currently has an ad deal with Digg and Digg might be acquired by Google soon, possibly nullifying the contract (though I don't really know the legal ramifications of such an acquisition).
There's no forum discussion just yet, but the writer of this article wonders how well-targeted those Microsoft ads are ... considering she used to see weird ads on Digg.
