How much is too much?

Recently, Mama Kat has had a few posts about internet safety which have really hit home for me. I've always been a little paranoid about how much I share on the internet. I haven't really figured out how much I'm going to share on here. Right now, I haven't used any names, and I'm thinking that I'm going to keep it that way. I've been limiting the pictures I post, even though I usually love to show off my family and friends.

I know that I don't have a lot of readers right now, but I'm hoping to grow. So how much is too much to give away? And is there a point where I am not sharing enough? I started this blog as an outlet now that my life is so baby-focused. How much does it really help me if I have to edit everything I write about?
