When all is said and done it's simply about behaving ethically.
As Ermy (a UK social work blogger) has written:
‘If someone doesn’t realise that disclosing details of a visit on their own blog is counter to professional codes of ethics, it isn’t because they don’t ‘get’ social media, it’s because they don’t ‘get’ professional codes of confidentiality’.
