Because it is what your friends and potential friends are using.

It isn't really a noteworthy messaging app other than bring attached to a popular app.

> potential friends

Hmm. So it's the perceived "best place" as a default. Is there some "discoverability" feature as well?

He means in real life.

You’re at a bar. You meet someone. They ask for your insta username to follow/message you.

Making friends and meeting people is hard enough for most people. The added friction of not being reachable on the platforms people use every day for messaging isn’t ideal. It’s not ideal to say “Sorry, I’m philosophically against social media so I can’t give you a username, you’ll have to text me” - and then you risk alienating them.

(You’d be surprised the percentage of people who rarely if ever use SMS these days, all the young people I know use Snap or Insta to talk to each other)

group SMS/MMS really blows. It's not a surprise people look for alternatives, but man there are SO many alternatives all with their own niche.

Every time my kids start a new sport or class or group we all get a new "group text" app to download and babysit.

Very much an XKCD moment -

But why not just email?

For me, email has become a cesspool of garbage. It’s like receiving letters in a dumpster parked in front of your house that the whole neighborhood dumps their trash into.

I loved email. It was perfect. Now, for me, it’s basically unusable. I can unsubscribe from ten garbage subscriptions a day, and it doesn’t even make a dent.

This question feels out of touch and I'm in my mid-forties.

Yesterday, I saw a couple moving musical equipment into my building and asked who was the musician. The person said I could find them on Insta. I had hoped they'd be on Soundcloud, as I'm a musician and post my music there. Insta is what a lot of young people use.

Before the pan, someone I matched with on a dating app rejected me when I told them I don't have social media accounts. She accused me of being a psycho (saved me from a bad first date). This is how a lot of younger people (she was like 10y younger than me) see the world.

Email is for corpses, at least that's what I think they'd say if you suggested it. Someone up the chain talked about classmates. I'd expect they are a younger demographic and the email stink would apply.

I welcome being out of touch. The current trends seem ridiculous to me.

There's no practical difference between sending a message via Instagram vs via email. It's all just marketing. You probably can't even get an Instagram account without first getting an email account.

Wow. This is like a Black Mirror episode.
