Good posts. Aviation safety development is based on openness and frankness. While adhering to that leads to extraneous "naive worthless contributions" and other extra "noise", my feeling is that that is still preferable to suppression of possibly valuable contributions, for whatever reason. In other words, moderation could preferably be limited to obvious repetitions and totally clueless contributions. But contributions by people from a different field should IMHO be treated with some respect. There just might be nuggets in them.
