Regenerating effect of the Olympics

This article appeared in today's papers, and explains very well the point I've harped on about how sport can regenerate/rejuvenate backward parts of the hosting city, giving it a new lease of life. Just like what happened to Barcelona and Athens after the Olympics was hosted there, Stratford in East London is benefiting from the same effect -- from a 'sinkhole' into a potential 'silicon valley'!
