Business Cards for Blogs?

I have been considering creating business cards to promote Living on Ashley's Allowance. But because I do not sell anything or offer a *real* service per say, I am unsure if it would be beneficial in any way to get my blog out there even more to those who may have an interest in my content.

What do you think? Do you use business cards to promote your blog? Besides utilizing the internet, do you promote your blog in any other ways?

Any and all suggestions are much appreciated!
