ReadWriteWeb, a blog about web technology, has a post by Richard MacManus this week about ://URLFAN, which ranks websites by popularity based on blog mentions. As MacManus explains:

We noted in our original review that ://URLFAN’s ranking list will inevitably be biased towards users of social media – and in particular bloggers. That’s a relatively small proportion of the world, however we think it’s still a useful index because social media users are highly influential. With that in mind, which websites are currently ranked the most influential on the Web?

://URLFAN is, as we write this, “currently ranking the popularity of 3,783,534 websites by parsing 302,023,552 blog posts from 5,948,937 blog feeds.”

The list below is ://URLFAN’s all-time top 10. The number in brackets to the right of each item is last year’s top 10 ranking (Nov ‘08).

#1. en.wikipedia.org (1)
#2. youtube.com (3)
#3. flickr.com (2)
#4. twitter.com (9)
#5. google.com (4)
#6. myspace.com (6)
#7. facebook.com (-)
#8. imdb.com (5)
#9. nytimes.com (7)
#10. apple.com (8)

There is one new entrant, Facebook at #7. washingtonpost.com moved out of the top 10, dropping from #10 last year to #12 this year.

Twitter is the biggest mover, up 5 places to #4.

….

://URLFAN isn’t a perfect measure of influence – you could easily argue that Google’s PageRank is far better. However we continue to like the concept and we believe it’s an accurate and up-to-date reflection of influential websites on the Web.

McManus references a previous post about super influencers, who tend to have outsized influence on others based on their numbers. That post discusses a 2008 report from Universal McCann, which came to its conclusions based on research among 17,000 active internet users in 29 countries.

Finally, super influencers are a worldwide phenonomen, according to McCann, but “there is a clear skew towards the emerging internet markets of Latin America and Asia Pacific.” Brazil has the highest rate of super influencers, with 24% of active internet users falling into the super influencer category. They are followed by India, Mexico and Pakistan, which McCann puts down to “how internet users have found their voice thanks to their massive use of social media in these markets.” . . .

There’s nothing really new in the report – we’ve known for a while now that social media is being used to create new forms of influence in the commercial and social worlds. But there’s good lessons here for brands and organizations that are still figuring out how to reach consumers in the Web age.

Obviously, effective public diplomacy takes into account the technology most available to the local populations – with cell phones winning out over PCs, in many cases. Still, the “good lessons” about how social media is creating new forms of influence are also applicable to governments and individual seeking to engage in diplomacy.
