For those of you who use an email address with a custom domain name, like first@firstlast.com, do you use that email address for every online account you create? It seems weird to me to do that if the email address is also my professional address and the domain is used for my professional/portfolio website, but maybe I'm overthinking it.

Sometimes I see top-level comments on a post that, from their content, appear to be replying to other comments within the post. Is there some bug that makes them appear as top-level comments rather than replies to the comment they're responding to? Or are people just bad at replying to the correct comment? I never see this on reddit so I'm confused why I'm seeing so many cases of it on lemmy.
