I was finally listening to this Chris Anderson podcast over at EconTalk re: Makers Economy.
Chris talks to the fabric of the internet and the true web generation, whereby sharing is ingrained.
In the past, tinkerers would sweat their projects, all encountering the same problems. You could go from city to city to see people tackling the same issues and hitting the same roadblocks.
With this interconnectedness of the internet you can see who else is working on it and work together and have additive innovation rather than parallel frustration.
For me this is natural and way more efficient, now imagine what it will be like once the 14 year olds of today are 24! Once they set their mind to something, a global community can work together to achieve it.
