I am on Instagram. I quit FB long time ago. The quality of forwards have deteriorated and I felt that is not the right place for me. I am still on social media just to keep in touch with all my friends at the same time. It does kill your time if you keep scrolling and watching all unwanted content.
My favourite is WhatsApp. Other than this am not interested into Facebook or Instagram. I have seen so many people just scrolling down and seeing the updates. It is such a waste of time.
I love instagram. Because I do marketing of my business through my Instagram account. I get to receive suggestions and feedbacks and appreciation as well.
