I noticed only recently that when entering an incorrect URL, I'm immediately transferred to the MSN search pages, with some lame statement that the URL I was looking for was unavailable, and whether I'd like to try to find what I was looking for through their search-engine.
"Oops. Google's getting too large a market-share, let's steal the dumb users away from them".
I hate their business practices. :disgusted Thoroughly.
