Selectively sharing or socializing online about shared interests or hobbies does not make you fake. Just fyi
Discussion
there’s a clear difference between coming here to speak about your hobbies and just two things you know you will get interaction on bc it’s popular here!
Any kind of pandering is kinda cringe. But if you post about a topic anywhere because you know that place will have folks that want to interact with your thoughts on said topic, that's kinda natural I think. Birds of a feather
