The airport code idea is a good one, however when the rare occasion happens that I do not know it, I just type it in my Google search bar and have the answer in a second, so its not such a big deal.
Otherwise I do not think this is a huge issue, at least not one that can be remedied by the TB. In addition to swings in the industry and peoples personal circumstances, there are also sikes whenever FT is mentioned in an article or on TV, as we have seen many times when issues come up. You are going to always have a certain number sign up to voice an opinion or 2 on the "big subject" and then fade away, that'slife.
