I must say that, given the name, my expectations when I joined were that it would be about (sci)ence (fi)ction in particular, not (s)peculative (f)iction in general.
Personally, I read quite a lot of the first, not that much of the second, almost none of the third (although, yes, the borders are very fuzzy at times). So, it would feel more at home if this was mostly with a dab of sf where the borders do blur, instead of full-fledged sf.
