Hey Jayden!
After reading your post, I liked when I know how you managed your facebook and Instagram. I am also maintain the private setting for my Instagram to protect myself. Because I had more control in my instagram, I am not often to use facebook since I believe it is not convenience and is open by anyone. I only post something very formal and not very represented to me in Facebook.
I also used linken for professional approach！I find it very convenience and very professional. After graduate from the college I start to reduce the amount of the activity in the social media, I will use Linken for Professional approach and Instagram for personal approach, which something we chose same.
