The internet doesn’t need much more of an explanation than this really:
Some call it web 2.0 but it’s more than that. The proof’s in the pudding.. went to www.clagnut.com (ex-colleague’s site) -> saw eleganthack.com link -> followed it -> saw this video from Kansas summarising what we (all) do online and what the web really is about -> opened up our blogging software (wordpress) -> copied the code from youtube.com into this site -> wrote this -> 5 minutes -> no techie knowledge required.
It took me back to when I was giving a training course at Multimap on XML to some of the client services team. I asked the question what happens when web pages are written in XML that any machine, program or person can interact with.. it was a rhetorical question, not any more: we’re nearly there.
