The growth of Facebook has been given another boost by the social network's acquisition of mobile start-up Snaptu for an undisclosed sum.
No big deal, you may think, but as ReadWriteWeb's Paul Butler points out, people accessing Facebook via their mobiles are twice as active as those who engage via PCs.
It was Israeli outfit Snaptu who earlier this year built a feature-phone app for Facebook, extending social network access to thousands more devices and into markets where smartphones are less prevalent.
The other big beast in that battle is the subject of David Carr's excellent New York Times piece - The Evolving Mission of Google.
Despite its insistence that it is not a media company, Carr makes a good case that Google is, and why that's more than a matter of semantics.
The gravitational pull of Google and Facebook has already had a huge impact on the way news is distributed, and they're both attracting vast sums of advertising cash that would otherwise have gone to the newspaper and magazine businesses.
At the same time, Google acknowledges that it depends on high-quality content and has "a responsibility to encourage a healthy web ecosystem", according to a spokesperson Carr quotes.
For newspapers and magazines struggling to make money from the link economy, that assertion might ring hollow, especially if the ledgers show their own days in the ecosystem might be numbered.
Planets Google and Facebook have pulled money from the press to the traditional web and now they're doing it again in the mobile worldo.
According to the folks at Guy Kawasaki's Alltop, Google's algorithm has "had more impact on the shape of the web than anything or anyone since Tim Berners-Lee" and this infographic attempts to show how.
The casualties of this shift in fortunes will be replaced, of course, hopefully by something better. But as we've seen with recent natural disasters, the consequences will be traumatic and restoration will take a long time.
