FB groups aren't all inherently bad imo, it's just a matter of finding one that suits you, if any.

I hang out on the FB group for the "What The Fat?" book series, in which authors and LC identities Grant Schofield and Caryn Zinn sometimes post. It's a tidy little gathering of mostly Kiwis and Aussies, without so much traffic that it gets overwhelming, and not so little that it becomes pointless. A nice little complement to this forum which allows for deeper discussions with a wider audience.

I think I could only imagine getting more involved in other social media groups if I felt I had nothing better to do. But I'm way too busy for that right now.
