From looking through different conspiracies I have found two similarities. First, everyone one of them want the conspiracies to be true and they all think they are seeing things that everyone else is missing, making them to try to further see things that aren't there.
There are some very good questions regarding the 9/11 conspiracy (the fact that Bush needed 9/11 to do just about everything he has done so far) but that isn't proof by any means.
