Yahoo Groups or GenealogyWise?

I really wonder which one is used more.... I joined a few more Yahoo groups for genealogy. I had to unsubscribe from the Transitional Genealogists forum because they do not have a digest version and I was getting bombarded with email. I really like the APG forum and for the most part the discussions are really useful. I like the fact that GenealogyWise is only for genealogy. I need to see if there is a writer's group on GenealogyWise.
