Talking of interesting innovations with the power to spark further (and potentially bigger) movements...
...check out Wedge Card in the UK, a scheme designed to boost local shops over big chainstores.
...and look at Book Mooch, which allows members to swap book they have read for books they want to read.
Both simple ideas that reflect macro trends towards local, connected communities and away from wasteful, atomised living.
In keeping with that vibe, and in response to Seth Godin's encouragement to buy handmade gifts from people we like and respect...keep an eye on my friend Jade who is soon to put some of her cool craft creations on sale.
