I feel like I could talk for hours about that post, and what's wrong with it.
Let's start with the title. It almost has nothing to do with link building and everything to do with link baiting. No problems there, but they should just call a spade a spade, and not try and tell us it's a pitchfork.
I think it is really short sighted in terms of "established websites". The methods investigated in the article, are well researched and the author gives us a clear path to follow. BUT, he neglects to point out that his methods will only work for a very niche range of websites. Anything corporate may as well skip that article, and most websites, that cross my path, are corporate.
Going social and being funky and posting blogs is all well and good if you have a social brand (like a Dominos or Fitness First). They can offer % discounts for likes, or Funky Fridays where pizza's are half price if you use their social media code. Great. That's brand building and that works... But what if you aren't a brand? Social stinks if you aren't a brand. It's almost worthless (and could be less than worthless since you'll sink time/money into it for no conversion).
What if you are an established law firm, as an example. Sorry but, posting blogs (i.e. generating content for search engines) is really a counter-productive process. If your content (what services your company has to offer) is already established then how are you generating new content exactly? Are you making stuff up? Padding pages to build additional keywords on the page?
And... Guest blogging? Who would have time? And the social stuff? Are you gonna offer elderly people a 10% discount off their Will and Testament if they Like your page? Gimme a break!
The author's post neglects all of these specifics by staying in it's broad path and telling us very little new information and how it will suit individual businesses. Quite frankly it suits branded niches and nothing else.
Social is kids playground stuff. Business CAN be conducted but if it isn't in a playful way that interacts with people having fun it isn't going to work. The nature of most websites is that once they are established so is their purpose. Creating content beyond that purpose, is creating content for search engines. What those companies need is links. How do they get em? It sure as heck ain't 6 months worth of link baiting.
If anyone needs evidence that social doesn't work. Facebook itself can't even make money from the monster they have created. They have 1 billion users and because they cannot convert them into sales they've made a loss of $157 million in their first quarter --- It's hype and pretence. People talk about this big social thing and it bringing in business. It doesn't. It really doesn't convert (well it might if you are Domino's or similar).
Don't even get me started on the whole link pruning ... If I was cynical I would guess that is the link bait reason that the poster wrote his blog post for in the first place. To sell his link pruning services. He sure as heck follows it up more than once in the comments...
