Blogger makes it really easy to use Adsense.
But also have a look at the revenue-sharing social networking sites like
Squidoo and
HubPages.
I've used Squidoo more, so I'll talk about that, but hubpages is similar. The have adsense built in, you don't have to do anything to set it up. They split all the revenue they make from your pages with you. But they have lots of other ways you can make money too, and it is all incredibly simple to set up. You can can sell Amazon books, various items from other web stores. Even airline tickets and accommodation bookings if you are into the travel niche. Everything that sells through your pages you get a commission on.
It's a lot of fun using Squidoo too.
