Lists (in Facebook) suck - they UI is hidden and terrible.
Facebook Groups came out when the author expected Facebook to respond to the concepts behind Google+ Circles. It turned out that it wasn't a response to those concepts at all, and was something unrelated.
Since the author doesn't mention Facebook Friend Lists, I can only presume that he doesn't know about them otherwise they should be top of mind when looking at Google+ Circles. He even talks about "copying circles" even though they are already in the product. I'm not sure why you think he knows anything about them? Did I miss something in his article?
Yes! I use facebook much more than I otherwise would because of the Friend Lists feature. I assure you that the users to whom this feature is important have found it. I presume that Google somehow believes that the rest of you will suddenly be super impressed with this feature now it is brought to your attention.
