I can't remember what Madison Avenue Ad man (aka Mad Men) is responsible for the quote "in tits we trust". Ogilvy ? It's a tasteless quote, but I can think of many companies, like GoDaddy, that use this strategy shamelessly at first. The links above are by no means that extreme, but I suspect it did help your marketing success.
Thinking of my own marketing, I don't even have a photo of a human being using our product. I'll work on that.
edit: added Mad Men reference.
