I started one for a friend and a few years later she's writing cookbooks and giving seminars. She's turned it into a full time job and she takes good care of me as a result. These days it's just maintaining it, just added an affiliate program.
She just hit 15k daily uniques, with the majority of traffic originating from the social networks.
If you are into Paleo, Gluten Free or have kids with allergies you'll enjoy her recipes.
