Well web2.0 worked for me. For someone who spends 10+ hours a day making web-sites I could not imagine actually visiting another web-site just for (blogger?). After using facebook to giving cans of virtual beer (?) at my mother-in-law, then I guess the term 2.0 is working. So someone has to start marking out 3.0 space.
Odd that search and brute meta-sources are coming into. I remember Tim Berners Lee banging out about semantic web in www7 last century. And there is the meta-data that won’t die. I guess that richer meta-data is really what made google work – just not in the way that most people thought it would with their massive hierarchical thesauri of terms. So what is the next ‘killer meta-data’?
