*Outside comment I have no opinion personally about this article or its referencing, but your disagreement seems to be for a large part due to the inclusion or not of a reference to a blog. Please note that most blogs are not considered to be reliable sources and cannot be used as such. However, the important word here is "most": some blogs are reliable sources. If you are uncertain, I would recommend that you ask for an opinion at Wikipedia:Reliable sources/Noticeboard.
