Eh, I disagree that dusty, under-used spaces are a negative, when you're on a spiffy new thing like this that nobody has heard of yet. (and that still feels like alpha release software)
I subscribed here with the idea it would be slower and quieter than the generalist space subs, but would be where I could come to discuss NASA-specific missions if I wanted.
Like, if I find an article on a NASA mission, I'd post it to a larger space sub. If I have a question about that mission, I'd post it here and wait.
