If the descentralization of social networks continue, we will have to prepare for the eventual rise of the instances wars, where people will start to fight about which instance is better and which one is weird to be in and so on, but that’s for the future of us all.
I chose my Gmail name when I was invited to it (it was invitation-only at the time), and it’s not the greatest name. I use it because I have decades of tuning it with filters and rules. But when Microsoft launched “outlook.com” I made an account with my real name as soon as I could, which I use for resumes and similar reasons.
I no longer assume Hotmail users are less literate than users of other email providers. Gmail or iCloud seem to be the default platforms for illiterate people today. Who only get an account because they have to for their phone. It’s so weird to me that my kids think email is archaic. I was a teenager before my family got email. And yes, we had one family email address. We had one family computer and one family landline. I was in college before I got my own email address and telephone number (thanks to my dorm Landline). Yet to my kids, it might as well be a fax machine.
