If you care about your online presence, you must own it. I do, and that’s why my email address has always been at my own domain, not the domain of any employer or webmail service.

I’ve always built my personal blog’s content and reputation at its own domain, completely under my control, despite being hosted on many different platforms and serving different roles over the years. It has never been a subdomain of any particular publishing platform or host.
