"web broswer download" on Bing gives chrome, opera, flock, safari and firefox.

Hmmm...

Actually, for me it gives: #1 http://www.linux.com/download_linux #2 http://www.hungrypenguin.net/downloads.html (which lists a lot of Linux variants). #3 http://www.linux.org/dist/download_info.html there are also direct links to Linux Mint, X Os Linux, Damn Small Linux and Puppy Linux.

That's peculiar. Are the results skewed according to the geographical location of the searcher, you think? I'm in Singapore.

So what? The algorithm obviously heavily weights search terms in a URL. I doubt this is some sort of conspiracy.

Me neither, especially since after that I did searches for database servers and web servers and they served up links to Apache and MySQL rather than IIS and SQL Server, but I thought it was an interesting contrast nonetheless.

Makes sense. Ubuntu's currently the most popular distro and Google incorporates clickthrough into their recommendation metric IIRC . Even if Bing does too, it hasn't hadn't enough time for it to be a significant factor.
