I think some people are interpreting different things from that article, and I think some people are interpreting different things from my
post too.
I could be mis-interpreting the article too, but here is my view. The thing I picked up on from the article, was the issue of web usage statistics...
"if you have enough usage data, you may not need to base your view of the web on that perspective (edit: i.e. linkbuilding, typical SEO) since you can use actual surfing data to help influence the search results."
This might have nothing to do with search engines or SEO efforts, it is about how many people visit different websites, and google is already monitoring a good proportion of this (analytics, toolbar, etc).
What websites get loads of visitors even though they might have poor SERPS (natural search engine rankings)? Websites that people already know about through other means, websites that have brand awareness (gained from possibly many different forms of marketing, PR, advertising).
The article mentions radioshack in the US recently ranking for electronics. A site people would expect to appear for electronics but perhaps wasn't until recently. Perhaps that change is due to google looking at the seriously large numbers of visitors the site gets, going through its electronics pages?
In the UK, if you search for
buy paint the B&Q website (diy.com) is nowhere to be seen (not the first 10 pages), but if you ask anyone on the street where can I buy paint, they will say B&Q or Homebase. Perhaps there are thousands of people checking out the paint on B&Q's website every day due to the company's brand awareness.
I think that what the article is getting at, is that making more use of the website stats that google is monitoring, there might be a time when sites like B&Q get on page 1 for buy paint, nothing to do with typical SEO, or brand directly or even the name of the site, but due to website user numbers, an indirect effect of brand awareness.
Of course people could get the wrong end of the stick completely and say the reason B&Qs site is not currently ranking for "buy paint" is because it is not using its B&Q brand in its domain name diy.com - but I do not think this is the case, it is probably not ranking at the moment just due to either bad SEO or not bothering to target the term. But I do not think the article is about changing your emphasis on what words you promote in your SEO efforts (brand words or key words), I think the article is about something very different to that.
