Fair comment James.
Yeah did not use the service myself, but did experiments to see how it worked.
The idea of having a plugin inside your WordPress site, so you can very quickly source new guest articles, was a neat idea.
However Matt Cutts has been giving warnings about Guest posting for the purpose of building links for some time now.
Like always, when people find a thing that works like guest posting, the usually flog it to death.
A lot of these legacy posts will be suffering from Hummingbird too, as they usually heavily focus on a singular keyword per post.
Still feel there is a place for quality guest posting. The emphasis on Quality.
Interesting developments.
To be honest I was not a fan of My Blog Guest, most of the sites were low quality and had poor footprints.
I know many SEO's did rely on the service which was dangerous in my eyes.
Overall the action from Google was fairly harsh, and I do feel sorry for Ann Smarty as she seemed nice.
