To me a FB fan page is unlike anything else out there. It's not an email list, though some people use it like that. It's not a group or circle, although it kinda works like that also. And it's not a one-way tunnel.
I liked this article, but I wonder if the real power of Facebook Fan pages isn't communication happening the other way -- getting feedback from your readers and fans. It also would have been nice if the author could have told us a bit about his real-world experiences before tossing out the list. How much did these tips help him, in real numbers? Advice is easy. Proven advice is much more difficult. This article walked the fine line between being useful and just restating generalities. It was difficult as a reader to tell.
In regard to your point on feedback, I totally agree that is the most powerful thing that you can get from a Facebook page; however, you can't get feedback if your fans don't receive your messages. Multiple case studies have shown that 90-98% of fans never go back to a page after 'liking' it, which means that in order to get this feedback from them, you must conquer EdgeRank. If you have any other feedback I'd love to hear it.
I've also always stuck to only posting once or twice a day and mostly never in the weekends.
