Wouldn't it be Nice if I Could Choose

Wouldn't it be nice if we could select our own specific ads that come up with our blog posts? So often I write a post and I think wow, an adsense link to whatever specific store or service I happen to be thinking of would be really great here. I notice on another site I use that my adsense is mainly about "blogging" "making money online" "get rich quick". These things often have little or nothing to do with what I'm writing about. I post a lot on the topic of parenting, babies, pregnancy, and things of that nature. It would be so convienent if I could select a babies r us ad to go there or a food network one when I'm writing about cooking. I really enjoy blogging and adsense is such a wonderful tool. I just think it would be nice.
