Currently working on social marketplaces (ad-hod associations) and came across this interesting piece over on experientia’s blog (actually, it links to vodafone’s receiver). Interesting stuff, we’ve been thinking about cognitive surplus mixed with a renewed conscience of doing the right thing, mixed with the renewed desire to participate and qualified by the renewed interest in sustainability, self-sufficiency and the desire to make stuff.
Tinkering is about seizing the moment: it is about ad-hoc learning, getting things done, innovation and novelty, all in a highly social, networked environment.
What I like about the idea of tinkering is that it can start small and almost by accident. You could be tinkering away at solving a problem and could quite easily join forces with others you meet by chance online. Who knows where it goes from there ;-)
