Martin Wolf at the FT was always careful not to correspond with me on his Exchange - though i was evidently streets ahead of all the other 'exchangers'. Intellect intimidates. Incandescent intellect scalds and sears. I ended up calling him an apostate, a Judas on the payroll of the Butchers of Beijing, and a shameless apologist for their misdeeds. Though he often openly insulted other contributors, usually with good reason, he never dared to try that stunt with me! We go a long way. Now, in his old age, he has grown wiser. Thankfully.
