If you wrote something interesting in the post it might encourage people to comment. My point being if I am the only one that bothers to comment it doesn't mean you and I are the only humans (assuming you and I are human). If you want people to engage with you you need to write something in your post worth commenting on AND (more importantly) engage with other people on their posts. Also, some friendly advice: posts like this (with multiple tribe tags and nothing to say are liable to get downvoted by people in the tribes for not being relevant. Be careful
RE: Human? See this? Comment. Please.
