Oh god what are you even talking about? Use Linux or not. What do you care if it takes off or not? I have no doubt that my family and non-tech friends could use a user friendly distro. Most don’t even use computers though as everything is done thru their phones these days it seems.

I use fastmail with several different domains associated.

• Personal email shared with friends and family
• Professional email - not my work but the one associated with my Linkedin and such

I have a custom domain just for signing up to online services. For me, this domain is completely separate and I never use it for anything else. Like nachtigall, I use a naming scheme and a catch-all address. My naming scheme uses their domain plus a random bit like so, twitter.6cruzbms@mydomain.tld.

There are two main benefits to using such a scheme imo. First, it’s harder for data aggregators to collate and cross reference me across the web by using an email address. Second, it acts as a hacked canary and it’s easy to identify the source of suspicious or problematic emails.
