When you use Instagram do you see ads or posts from people who aren’t your friends or family members? I’ve never used it so I’m not sure how the algorithms work.
Personally if someone is my friend and has something worth sharing they’ll tell me about it directly or send me a picture. I don’t feel like I’m missing out on anything. I’ve had people I was friends with move and we’ve lost touch and so forth. I don’t see a reason to struggle to try and stop that myself. Been pretty happy this way but that is what works for me.
I also get messages or pictures from people I'm friends with, but for people who are more acquaintances, I follow them on IG and see what they're doing, and if it's interesting I'll comment on the post or message them, and catch up with them that way.
It's also somewhat of a hassle to send messages and photos to people when you want to share it broadly, such as a trip you went on or something. People might also not necessarily want to see what you're sending all the time, so an IG post is an easy way for people to follow you and what you're up to.
You can almost think of it as RSS for your friends and family.
Again just my perspective but I don’t see value in broadcasting experience to a wide audience. I would view that as “content”. I don’t think it has any positive qualities. The RSS feed is a good way of thinking about it, but I say just don’t post and who cares about your trip ya know? If you don’t care to tell someone in person or over a phone call or some other directed means I think you don’t need to share anything. Again just my perspective on that. Which is why I’ve really only ever used Twitter to complain into the void from time to time.
