As mentioned in the article, and I recall from when I was more heavily invested in the stock market, Bing cost Microsoft billions of dollars every year in lost revenue. We all knew that. But this article goes on to say that it's hard to figure how much Bing brings in and they are only going by what Microsoft says and Microsoft says it's "profitable".

Well, profitable could mean by a dollar, and I don't see any shouting from the rooftops by Microsoft. I also don't see, as someone else brings up, much in the way of their presence in my server logs either.

What really gets me are all the articles that appear on MSN but really turn out to be searches with Bing. Don't know if they still do that. I don't use MSN either.
