why is it that the majority of personal sites offerring web design / development services give the impression that they are more than just a one man show ? The tendancy is to to use "our" and "we" instead of "my" and "I".

I could understand if people were bidding for large contracts, where the illusion of having a larger company would impress a client but the majority of these designers are just starting out in the business, they are likely to be bidding for small sites for small companies so their prospective client base is not expecting or necessarily willing to pay the costs of contracting a fully fledged agency, with associated overheads.
