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.

I have a Hotmail account for the same reason. I've got a few things that still send to my Hotmail, like government and banking stuff, so I've just kept it. Outside of work, I don't email much anyway so it's not much to look after 2 accounts.
