Although Google obviously won't be releasing it's search algorithms it might well release the code for things like the Google FileSystem (PDF) which may benefit a lot of people.
I totally disagree. I think the GoogleFS is a much more valuable commodity than the search algos. I mean, frankly, I doubt think the search algos are that brilliant, past the initial lightbulb of PageRank... just refinements and optimizations. The tough part is harnessing the -insane- computing power necessary to serve the world's searching needs, and doing it cheaply.
Despite that, I do hope you're right, and maybe you are... since the distributed FS/OS they've developed is, like I said, so much more valuable. What good would search algorithm descriptions do anyone except aid their competition? I can't stick Google's algorithms into anything I have... but a nifto OS that can combine a few computers and let me run stuff across them trivially? -THAT'S PRETTY COOL-
