I think that Instagram is a great app. You can share your pictures with others, communicate with them there; the only thing that can bother people is their privacy. For example, when you want to share very personal, family photos with your closest people, but don't want others to see them. I always thought that there was no apps that will allow you to share photos and control who will see them, but when I went looking for the info on this topic, I found this article https://www.splento.com/blog/splento_app/how-does-the-splento-app-help-keep-families-connected-even-when-living-far-away/ about Splento, and their app which allows you to choose with whom to share your photos. I've tried it - it's amazing!
