No plan survives the first contact with reality.
That's why Venture Capital investors don't put money into ideas or plans, they put the money into people. With the hope that the entrepreneur will not stick to a plan, but adapt it.

I wasn't part of the planning committee for this site. But I can see that it is not over-bursting with life. "Traveling Dommes" for instance takes me back almost 5 years.
