Here's a quote from Mark Leonard that I particularly like:
"[R]enewing Britain's identity does not mean inventing a completely new image of Britain or doing away with its heritage and tradition. It means regalvanizing excitement around Britain's core values - as a democratic and free society in an interconnected world - and finding a better way of linking pride in the past with confidence in the future."
Sounds like wise culturemaking advice to me, and neatly ties in with this.
Perhaps nostalgic identity brands might also want to take note.
