At Headshift, we like to concern ourselves with big, deep issues that teh intarweb tends to raise if you take a step back. Issues like the emergence of order in complex systems, how to take the next steps towards the holy grail of the Semantic Web, and how to define this Web 2.0 term that has gradually pervaded the collective consciousness of the blogosphere.
Well, it' s heartening to know that The Register readership has cracked it - the results are finally in on their What Is Web 2.0? Poll. Feed to your marketing department one page at a time :)
