Kerri has a nice blog, The Wish Jar Journal.
I found the Ad Free Blog organization among Kerri’s links. Can’t really join it with a Google/ Blogger blog. But maybe my WP blogs could join up. I don’t think ads for your blog software or host would count. 
By using this icon on my website I am stating…
1. That I am opposed to the use of corporate advertising on blogs.
2. That I feel the use of corporate advertising on blogs devalues the medium.
3. That I do not accept money in return for advertising space on my blog.
