I just wanted to share one of my favroite TED talks titled: Where do good ideas come from, by Steven Johnson.
In this talk, Steven Johnson talks about how "Eureka" moments come from spaces of creative chaos. Spaces where people bump elbows and are exposed to ideas and inspiration they would not have otherwise found, had they not been in that one coffee house . He attributes the evolution of the London crack houses to coffee house and finally they virtious tea house ;) as the place where good ideas come from.
So, check it out!
