My name is Themba Dlamini from Margate KZN. I have a similar network like this one, www.phuzemthonjeni.com. I have found these networks valuable in keeping dialog going in the country and help to uplift each other.
I have learned that these networks are powerful in breaking racial barriers because they cross between social and formal.
What you say in your introduction could not be further from the truth.
However, in these networks you must extract what you can. Not everything is FOR you.. so just take what you can and continue to mind YOUR business.
