WordPress.com support Google Adsense?

Can WordPress free hosting support Google Adsense?

Tonight I searched all about Google Adsense for WordPress free hosting like mine. Yesterday I read one book about Google Adsense bussines and this is made me interested. And because my first and succes blog in WordPress like this, I’m very interesting to register Google Adsense and add this to this blog.

I founded one article about how to register and add Google Adsense with WordPress.com blog. I think its very work. I dont think so if I must register and pay new domain. I dont know why I should register for new domain. But new domain must be pay per years and I never want to add my domain blog.

I really don’t know. Hope WordPress will give suprise that can make our blog support adsense programs.
