I think it's been discussed to death on here for the last 4 years (we pioneered the idea of long primary no secondary and the myth of autloysis here), and there are literally thousands of discussions on this site about it. With most of them having great info usually contributed by me in there. This has been discussed, argued, and debated ad-nauseum, til there's really nothing more to say.
This thread is about the best, and has the most rescent discussions and info on it

More and more recips including some from Northern Brewers, those appearing in BYO, as well as online are beginning to recommend no secondaries and 3-4 week primaries, which reflects the shift in culture on this topic.
If you arbitrarily move your beer, like to follow the silly 1-2-3 rule, you will often interrupt fermentation. Because sometimes the yeast won't even begin to ferment your beer until 72 hours after yeast pitch, so if you rush the beer off the yeast on day 7 then you are only allowing the yeast a few days to work.
Besides, fermenting the beer is just a part of what the yeast do. If you leave the beer alone, they will go back and clean up the byproducts of fermentation that often lead to off flavors. That's why many brewers skip secondary and leave our beers alone in primary for a month. It leaves plenty of time for the yeast to ferment, clean up after themselves and then fall out, leveing our beers crystal clear, with a tight yeast cake.
