It's about Microsoft's new search abilities at their "Live" site. The author has obviously not become immune to hype yet, and depicts the whole thing as a battle between MS and Google. While it is that, right now it's more about delivering a decently comprehensive search result from the new site.
The FireFox support is not quite there yet so don't bother trying it, but I actually did do some searches using IE 6 and found it to be okay. Perhaps a bit slower than Google, but as I was searching for two really obscure Linux files (that I have not been able to find using Google) that may be forgiven.
Yes, I found my files and got what I consider to be fairly good results on several other searches, as well.
