Using ‘nofollow’ on untrusted (or unknown trust) outbound links is sensible and I think that in general this is a good idea. Like wise using it on paid links is cool (the fact that all those people are now going to have to change from JavaScript to this method is another story…). I also believe that using ‘nofollow’ on ‘perfunctory’ pages is also good. How many times in the past did you search for your company name and get you home page at number one and your ‘legals’ page at number two. Now, I know that Google changed some things and now this is less prominent, but it still happens. As much as you say that these pages are ‘worthy’, I don’t agree that they are in terms of search engine listings. Most of these type of pages (along with the privacy policy page) are legal ease that just need to be on the site. I am not saying they are not important, they are (privacy policies are really important for instance), but, they are not what you site is about. Because they are structurally important they are usually linked from every pages on the site and as such gather a lot of importance and weight. Now, I know that Google must have looked at this, but I can still find lots of examples where these type of pages get too much exposure on the search listings. This is apart from the duplicate content issues (anyone ever legally or illegally ‘lifted’ some legals or privacy words from another site?).
It doesn’t mean than you have to advertise on these social media platforms. It means that they belong to that pyramid which will function better thanks to their support. Just secure them and decide which of them will suit your goal better. For example, you can choose Instagram because its audience is the most suitable for mobile devices and bits of advice of their exploitation distribution. 

As I was telling Norman above, these days what we’ve come to call content marketing is really a big part of “link building.” You can’t buy links, and “you link to me I’ll link to you” requests often land on deaf ears. Its really all about creating high quality content (videos, images, written blog posts) that appeals to the needs/wants of your target market, and then naturally earning inbound links from sources that truly find what you have to offer worth referencing.
“With 150 million pages, the Web had 1.7 billion edges (links).” Kevin Heisler, that ratio holds true pretty well as the web gets bigger. A good rule of thumb is that the number of links is about 10x the number of pages. I agree that it’s pretty tragic that Rajeev Motwani was a co-author of many of those early papers. I got to talk to Rajeev a little bit at Google, and he was a truly decent and generous man. What has heartened me is to see all the people that he helped, and to see those people pay their respects online. No worries on the Consumer WebWatch–I’m a big fan of Consumer WebWatch, and somehow I just missed their blog. I just want to reiterate that even though this feels like a huge change to a certain segment of SEOs, in practical terms this change really doesn’t affect rankings very much at all.
