A little late to this, but as the others say, speculative fiction is kind of an umbrella term that encompasses SF, F, H, and all the many vast and murky gray areas in between and around them. If you're fairly sure your work doesn't fall into Horror, I'd say this is more likely the better forum for asking questions. If you're looking for social interaction, I'd say hang out and introduce yourself in the SFF and Horror social threads (the
Cantina and the
Hounds, respectively) and see who you click with?
Otherwise if you can tell us more about what you're looking for, happy to help as we can to point you in the right direction.
