I think you should get rid of the word Beta. It's a "kid friendly" site that a bunch of moms are going to find through search. None of them are going to know what that means. That said, it probably won't hurt anything. I just think people go out of the way too often to let people know that their site should be treated like an unfinished toy. It's not a toy. You made something you think is useful. Tell them it's useful and see if they tell you otherwise.
Any plans on how you're going to make this a startup? Making money etc?
