This is a series of three articles – the first (this one) outlining the
significance of Web 2.0 technologies, the second article discussing the
impact of Web 2.0 technologies on mobility and the final article on the
impact of Web 2.0 technologies on digital convergence.
If you are already familiar with Web 2.0, my goal, in a nutshell (no pun
intended!) is to extend Tim O Reilly’s seven principles to mobility and
Thus, I will not attempt to add to the body of knowledge in terms of basic
Web 2.0 concepts themselves. I would rather prefer to build on some of the
excellent work done on the subject from folk such as Tim O Reilly, Richard
McManus and others. I will use their work as a background and extrapolate the
basic Web 2.0 principles to mobility and digital convergence (areas which I
am more familiar with).
My approach will be to ask a series o... (more)
Following my article about "Mobile Web 2.0," I wanted to find a
blueprint/case study of a Mobile Web 2.0 service.
This follow-up article is a bit of a gedankenexperiment – but I have
drawn on the excellent work being done by Dr Marc Davis and his team at the
Garage cinema research at the University of California (Berkeley).
The service I am considering here is a ‘mobile’ version of a
combination of del.icio.us and flickr
As you probably know, both del.icio.us and flickr are based on tags. However,
note that in a mobile context, a ‘tag’ would have a d... (more)
Welcome to the second part of this 3-part article. Much has happened since I
wrote the first part: for instance, I am now a member of the Web 2.0
Workgroup and I have also been selected to speak at SYS-CON's SOA Web
Services Conference & Expo 2006 in New York City in June.
Many thanks for all your feedback to the first article. I would also like to
introduce Tony Fish (who is my co-author for OpenGardens ). The authors of
this article and the third article which will follow (about the impact of
Web 2.0 on digital convergence) are Ajit and Tony jointly.
In this article, we will disc... (more)
Digital convergence is a much-maligned concept. Mention Digital convergence,
and it conjures up images of the intelligent fridge : a concept most people
think they have no need for!
But Digital convergence is an idea whose dawn is near.
There is a lot of confusion about what exactly is meant by digital
convergence. When people talk of Digital convergence, they could actually
mean different things:
a) Co-mingled bits : The original definition of Digital convergence as
outlined in Nicholas Negroponte’s 1995 book Being Digital
b) Device convergence: One device to rule them all! ... (more)
