Why do some people not use capital letters in their name?

Answer 1

some of them dont use capital letters at all so that explains them

but those who normally use capital letters everywhere except in their name may just be emphasizing their name in a peculiar way

More...I left the above original answer for a reason...

In the English-speaking world, tradition says that a person's name begins with a capital letter. This is by no means law. But it is most certainly a nearly universal custom, one that has never been seriously challenged. (Please, don't flame me, you fans of e.e. cummings!)

Recent changes in society, especially changes in the way we communicate with one another, have challenged many of the long-established rules of grammar and punctuation and capitalization. Specifically, the language has been altered in practice to fit new technologies like the internet, text messaging, instant messaging, email, and so on. Usage has been molded to fit these technologies, much to the detriment of traditional grammar constructs.

Internet URL's, for instance, must consist of lower-case letters. Ditto for email addresses. Such rules are not a conscious attempt to restructure the language, but are set up to accommodate programmers. Text messaging and instant messaging, done on the fly with PC or cell phone, are by nature done quickly and with little or no regard to correct spelling, capitalization, or punctuation. Even the most sophisticated search engines on the internet do not differentiate between lower- and upper-case letters unless they are instructed to do so.

I guess the best answer to your question is that, in many of today's communication venues, people simply don't have to capitalize anything, and have lost (or never gained) the discipline required to stick out those pinkies to the SHIFT keys.

Of course, we now have the curious phenomenon of those whose CAPS LOCK buttons are permanently "on," dooming us all to their perpetual YELLING. But that's another story altogether.

Oh, I left the first answer (above) because it so perfectly illustrates the non-use of capital letters AND the complete abandonment of punctuation. In our modern times, if it ain't a "dot" or a "slash," it ain't squat, it seems.

Answer 2

Some people may choose not to use capital letters in their name as a form of self-expression or to stand out from traditional naming conventions. It may also be a personal style choice or reflect their cultural background or artistic preferences.
