Back in the early days of the internet, there were a bunch of webcams anyone could view - sometimes a street, sometimes the coffee machine of a lab, and, occasionally, someone's bedroom or appartment. Although they were much talked about, I'm sure it was a tiny number of people, and probably not for very long. And because of crappy bandwidth, most of these cams were more like constantly updating image, rather than actual video. Tbh, maybe it's not even a real thing, but I definitely remember it being spoken about.
Nowadays obviously things are great for people who want strangers to know what they're up to, they've got countless media to choose from. And 'watching a stranger do mundane things' was packaged up and sold as reality TV a long time ago.
But I guess my question is, are there people still live-streaming their life - without it being a sex thing (like onlyfans) or advertising / shilling front (so, ruling out most 'influencers'). Are their folks out there just running a 24h twitch channel where people can watch them fold their laundry or doomscroll the night away on a poorly illuminated couch?
I don't see flirting as very different from making friends. The two biggest differences would be speed and boundaries.
If I'm trying to make friends, I'd be mindful to not seem too keen and obvious, which is also generally good flirting advice, but sometimes you can be extremely obvious with flirting (the "nice boots, wanna fuck?" approach). I'm sure there are situations where saying "I want to be your friend!" is a good strategy but they're pretty damn rare (and probably involve been on mdma).
When you're building any relationship or connection, one of the necessary steps is breaching boundaries. By sharing personal information (whether it's hobbies, or a personal tragedy) or making jokes or teasing (if appropriate and appreciated) helps move a relationship from "stranger" to "friend", similarly eating together, inviting someone into your home, or physical contact all represent breaking down boundaries and closer and more personal relationships.
Different social groups have different ideas about appropriate behaviour at specific levels of relationship. I have social groups where being 'cheeky' and even outright mean to a new person is how they show they're one of the gang. Similarly, there groups of people who can be lifelong friends, but still wouldn't be comfortable hugging. For many people, flirting, especially if you're aiming for a sexual relationship, often involves more physical boundary testing than with platonic friends (letting your hands touch, flicking dust off their clothes - and just FYI, if you're not sure what you're doing, it's almost always better to let the other person be the first to initiate physical contact, especially if they're a woman). But saying that, some straight guys I've known are very physical with male friends both with hugs and friendly punches, so it's not a strict line.
