The first time I've scrolled through the title I've read: Netflix uses NetBSD and I thought that's strange. When I had to re-read the title and realized it was using FreeBSD I wasn't that surprised.
FreeBSD is a natural choice if you want stability, even over Linux. I enjoy their update scheme although the lack of an official 'pkg' repository gives in to my nerves.
So, why is this news, is beyond me...
ps. I see a lot of people complaining that they use an open platform (FreeBSD in this case) to create a closed product. If I'm not mistaken (I'm not a US citizen and Netflix doesn't work in my country) it's a media-content rental service. So what exactly is the open source alternative, www.PirateFlixbay.org? :-)
