--->"Count up the number of structural engineers AND structural engineering students AND the number of structural specialists."
As stated, the only thing that would much matter to me (if I were to give this much credibility) are structural engineers with extensive experience in how buildings can collapse, particularly skyscrapers. For all we know, many of these titles could be persons with a 2 year degree in home building. Students are students. They're not experts or even seasoned engineers yet.
--->"How many structural engineers do you think are even aware of the website?"
More important here is why aren't 99.9% of structural engineering professionals in the world not screaming at the top of their lungs (through their own associations) if the Science (as 911truth says) simply doesn't add up?? If its so simple, then this organization would not need to be "found" on the Internet or created. Existing associations would have been all over it.
So many Conspiracy believers wrongly assume that they are the are enlightened ones because they have high speed web. If anything, it has sadly led them many astray by flaky organizers and fraudsters who use the web to propagate political or financial agendas. If its on the web, it must be true. There is some great information to be found online, but by far (even in this electronic day) I find most truths are still hashed out offline.
--->"Meanwhile, the number of signatures continues to grow.
The fact that it still remains a fringe org 7 years after 911 tells me it doesn't have much traction. It may continue to "grow" but the reality is its growth is not indicative of anything compelling.
