May I say that in my experience those who are genuinely well-informed have no reason to attempt to impress by disclosing details of their personal lives or of their academic prowess. They share their proficiency in the knowledge that, to the intelligent reader, their posts speak for themselves. Those intent on creating a ‘persona’ for themselves can claim to be anything they like – but to the intelligent reader their posts speak for themselves too. Ultimately, we are all anonymous.
