I have been collecting these for a while. One site here, another site there. As I click through the items in my feed reader, I not only read the posts, but I look at the site. I look at the ads, the layout, and the content. I also look at what networks the blogger belongs to. At first, I found only MyBlogLog, BlogCatalog, and Bumpzee. But now there are a few more. At least enough to write a post about. The requirements for this list were simple. They had to be more than a bookmarking service. A visitor widget got you in. A related post or blog widget got you in. A way to add your feed to a public profile page got you in. Being an SEO/Marketing friendly community got you in. But the list is raw and still being built.
Your Local NewsPaper
The last one you will have to find on your own, but it can add visitors, local ones, who may subcribe just for that fact.
I will be updating this list and adding details in a future post, but for now, you may find a few networks you never knew about.
