Over the last few months, Mayor Herman Mashaba has been communicating his vision for accelerating the rejuvenation of Johannesburg's inner city. He has met with business people and property developers and challenged them to turn the CBD into a construction site. He has committed to tackle corruption and improve the enforcement of the city's by-laws. He has said all the right things about harnessing heritage sites and reusing old buildings. As a result inner city enthusiasts (and I'm sure many residents and workers as well) are feeling a new wave of optimism.
