I'm interested in developing a database that could serve as the back end for a site dedicated to documenting and organizing facts, questions, and arguments related to the science of the destruction of WTC7. I am not a scientist, but I'm interested in doing this so that I can nail down the main points of contention about the destruction in context and in an organized fashion. I find this to be the most problematic thing about discussions which many times just jump from one topic to the next, with participants only hoping they've made a point, without any real idea if they have. I'd like to be able to clearly point to a node in the argument and say "here's where we disagree. are there any related (parent/child) arguments? can this argument be verified? what other information do we need to verify this argument?"
