Why do you use Goodreads?

I’m working on my thesis project for grad school and I’d like your help. I’m creating a business plan for a Goodreads-like online community that focuses on diverse books in speculative fiction–fantasy, sci-fi and horror.
The community/blog would be a place where readers can find non-traditional speculative fiction titles–books with POC, people with disabilities and those a part of the LGBTQ community. It would also be a place where authors can learn how to write diverse characters i.e. describing skin color, realistically portraying a blind character, for example.
I’ll be more than happy to share the results when the survey is finished.
