Blogging and seo go hand in hand and I have written quite extensively about this in several articles.  As to not get a duplicate content penalty for basically making the same post at all of these blogs I am making subtle changes to each post as I make the post.

This experiment that has nothing to do with domain SEO but rather with SEO as far as blogs hosted at various social networking sites.

The experiment is basically this. I am listing several links that point to various blogs I have at various social networking sites. Although this is not a controlled study I am hoping that it will increase notice of these blogs in the search engines and therefore bring more traffic to each blog. Except for MySpace and Friendster the others that are listed here have ways to earn income built into their systems.

Here is a listing of some of the blogs:

MySpace Blog
My Yuwie Blog
My MyVieWin Blog
My Narple Blog
My Friendster Blog
My RotatrixFriends Blog
My Zubby Blog
My Gizter Blog
My Yagatta Blog
My BizzyBlogz Blog
My Friends For Cash Blog
My Apsense Blog
My Ojeez Blog

In addition I have several blogs that are hosted on my websites using a Wordpress platform and others hosted at blogspot.com, now owned by Google. Some of these are:
http://www.opportunityassistance.com
http://www.blogsmart-resources.com
http://www.article-database.com/news

This list is not all inclusive. The ones that are hosted at blogspot and use the blogspot software are:
