As someone who has changed their tag multiple times only to go back to the original many years later, pick what sticks. You can come up with the edgiest, coolest sounding tag, but if it ain’t you, then it ain’t you. You have to imagine other people calling you that, and it coming out of your mouth if you’re introducing yourself at an event. When I think of doing that with some of my prior tags, it makes me cringe. Half the time people would mispronounce it and it would just make an uncomfortable situation, like do I correct them and risk looking like a tool? Do I let it slide and let everyone continue to mispronounce it?
If it’s something to do with your real name, then so be it. Honestly DJK is kind of a catchy tag, so if you remove the numbers you have yourself a decent tag. Better that Typhoon imo. But it’s your thing, you do you however you want.
