It's nice to see our discussion turn into a post. I'm a millennial, so maybe that's why I'm not familiar with slide nights. But yeah, I agree with you on this. Natural conversations have a natural flow to it. It can be discussing the different things in the picture, the outfit, the facial expressions, or the story behind it, there are a lot of things that come up. Every discussion can be personalized between those involved. But with social media posts, it is the generic replies of "I love your picture/outfit/location/something" mixed in with other similar replies. The author usually replies with a "Thank you" or some short reply, and most of the conversation ends there.
Yep - no issues there. But so you know, I have trip photos saved on DVDs too :D
And yeah, it is that depth of discussion, and then the side stories that come up from a single photo. The photo is not the point, it is the experience behind it. When it comes to social media though, there isn't the depth and people can't be bothered typing decent conversations in many layers.
I think we have some of those of when we were kids.
