I registered PAN.XYZ some time last week. It is renewed at a regular price of ~$10 even although it is a pretty short and meaningful domain.
The reason why I registered this domain is that PAN is my first name. However, PAN.XYZ does have another special meaning, which I thought of. Let me explain.
PAN in English is the word root for “All” according to Wikipedia, and we live in a three-dimensional world, which means all things have X, Y, and Z attributes in space. Therefore, PAN.XYZ means everything, every opportunity, the infinite possibility in life – which is my life philosophy.
