I thought the same thing but then I read the marco.org article and realized that it wasn't a response to the This Week in Batteries blog, but to an unrelated article that seems to recommend full cycling the battery. I believe what was meant by the marco.org article is that regular full cycling is a lot worse for your battery than simply leaving it plugged in.

The This Week in Batteries blog recommends extending the life of your battery by not constantly leaving it topped off at 4.x volts per cell (which causes the internal aging process to accelerate)

So in essence, they're probably both right. When people ask me what's best for their laptop battery I say charge it to 65% and put it in the refrigerator. Not so great for using your laptop however.
