Snacksby lets you input ingredients you have onhand and then spits out an appropriate recipe, not unlike fridge googling. Should be a great service, as long as users bootstrap it by contributing recipes. A Lifehacker commenter said as much, only not as gently:
"Great idea but completely worthless at the moment given that they currently have less than a dozen recipes in there and are relying on users to fill the database."
Soma (the guy behind Snacksby) put the comment at the top of the Snacksby home page and added "we've got more than 12, but he's damn right." Give the man points for chutzpah, and go add your favorite recipe! I just added mine.
