I find myself proselytizing. (Skynet comes!) So if friends and family see something at my house they like I reflexively tell them they can have a similar setup for free(dom). I want them seeing Ubuntu, maybe Mint, because I can't imagine them using anything easier on the non-programmer. And I use them myself; familiarity with Ubuntu quirks makes me look less like a Linux Dork who, like a fan boy, said it would be "easy".
So to add to Steve's list of questions: What would you want your granny to use?
