This is a great service. It is well worth purchasing. I especially love the edu blog posts and gov wiki pages. He over-delivered on those for me, which is really great. I also like how he is randomly linking from the edu and gov profiles to the edu blog posts, and then from some of the blog posts to the web 2.0 properties, and from some of the web 2.0 properties to the articles. Don't forget that he is also creating social bookmarks for each edu profile and other properties. If this doesn't increase your rankings in google, I don't know what will. One thing I would recommend though is that, when purchasing this service, you provide your own articles and posts for submission. I mean you could go with the articles he provides, but we don't know if google is also analyzing articles for grammatical errors and the rate of occurrence in an article or not. But, it's best to try and stay on the safe side.
I will update you guys on the changes in ranking of my website. I got the report on the 19th. So it is too early to report on that.
