No, they don't count because their claims have been thoroughly discredited. When you consider that there are hundreds of thousands of engineers and architects, if you got a few thousand to back up the 9/11 Truther movement, who cares? Out of a field of people with actual higher education and qualifications to give expert opinion on the subject, some few voices in the wilderness accept crackpot ideas, therefore the crackpot ideas are valid?
It's just like Michael Behe and other creationists who have actual credentials in their respective fields and who have used those credentials in an attempt to promote completely unscientific bullcrap, it's much the same with the 9/11 Truthers.
It's also telling that you dismiss the substance of the article simply because some people made comments on it that you don't like. Would you like to address the point, or will you concede?
Another piece of well researched evidence on the WTC 7 fire. So much for the claims that "there were only small fires that could not have caused a structural collapse".
