Paul Simmond’s piece (“Only we can save the world wide web”, SC July, p21) was unnecessarily alarmist and full of claims left unsubstantiated.

I am surprised at this lapse by a man so highly respected in theindustry. It was astonishing to read throwaway lines like “in the US, itis now said …” and “some estimates place the number of infections ashigh as 50 per cent”.

Who said what in the US and, er, which estimates would these be? He thengoes on to make a dubious analogy between the security flaws in theinternet and the medical profession. This kind of stuff has no place ina serious journal such as SC. Make claims, but make themquantifiable.
