Blogs Make Money?

I have currently started following a blog "Money Saving Moms" I know lame because I don't have any kids but she puts together deals from stores ie. CVS that with the use of coupons you can get free stuff. I started getting really into it. I just bought 2 battery operated toothbrushes and a tube of toothpaste ($16 value) for $3.92 plus I got $16 in credit to use at CVS later on. It's a pretty awesome deal when you stop to think about it and I (lamely) loved the thrill. So I was reading more of ther stories instead of just the deals. She has a blog and makes a "full-time" salary just blogging everyday. I'm impressed because honestly I can't even imagine getting paid to just write a blog about something you enjoy everyday. Does anyone want to pay me to read my blog?
