I don't think polls should continue forever. It's better to change them frequently, to keep things fresh, but also because it will be interesting to run the same question several times and see how results change over time. As various teams start to move towards flight, as hardware is tested or publicity video is released, or as teams merge or struggle with funding, how will perceptions change? Questions might be run for a month at a time, and at least some of them repeated annually, with results archived.
