Good background info. If people only read the technical material, we wouldn't have to wade through dozens of posts dismissing the idea as stupid.
Granted, the article in the original post contains too little information to make a judgment. Why people still do, beats me.

It looks like non-geek people are starting to pay attention. Here's an excerpt from a fool page.
"Speaking of doom and gloom, I'd like to let everyone know of the widespread scorn and derision the geek community has expressed towards the initial public offering (IPO) of LinuxOne Inc., future stock symbol LINX.
