I actually like the first one best. It seems like you want to sound professional and show what you've done. Zigga just sounds the opposite to me. A name on a website, that's a different thing, but you're really representing there in real life.
What will spark up a better conversation... a girl asking what zigga is, or why you have dotcomkid on your plate? Start talking about your beamer and all that and she's in your car and the panties will be on the floormat.
