Your own domain? I guess it would be a good thing to have. I think people have their own domain names, because it gives them the freedom to customize, and post anything they desire. If you are a professional, who needs their own domain, then you should have one. However, if you are a student, who aspires to be a professional, I do not think you should obtain a domain, at this time. Students tend to post things that can jeopardize their futures, and that should not be on a domain; that should continue to be a social media aspect. Students have no content to post on a regular, and have no site viewers, unlike an entertainer or public figure.
I am not sure whether my domain name will consist of my name, or an alias, because I do not plan on keeping it. I aspire to be a well-known journalist, and best selling author, but a domain is something I will require when I need to.
The domain I might use is CheRhys. Che Rhys is a play on my name.
