I think the point Mike is making is about being truthful. It's not really being honest if you portray your business as a multi person one if it a one man band. In the limited amount of marketing that I do these days, but have always done, I try to avoid words such as 'we' and 'our' etc. I don't necessarily replace them with 'I' and 'my', instead I try to find a way of expressing what I want to get across by using my business name.
