My latest book purchase has been Here Comes Everybody by Clay Shirky. Which basically talks about how technology (not just the internet) has made it ridiculously easy to get on with things, do stuff, bring people together and make the difference.
5 or 10 years ago it wasn’t so easy, it is now, if you really want to. It doesn’t mean that everything you do will make a difference. The cost is failure is now so low – it doesn’t really matter if things don’t go to plan. This makes it really easy and encouraging to experiment. And experiments can lead to wonderful things!
