I chose mine because i use it everywhere (email id's, logins etc.). simple to remember for me and my friends too.
...as in: "Your name is mud!"
Except in this case it's: "My name is mud!" 
Code = Charity Overcomes Destruction Everywhere.
Although Im a well and upcoming 3l33t haXor the name represents a pivotal point in my life.Mine comes from the Pixies song, Velouria 
Why did I choose it? Well it seemed a good name at the time. Alas, I've found it's as common as muck out on the intarweb 
My Name is Awadhesh, that is the reason behind choosing it.
You will guess it 
I was inspired by this name. But I came to know that some one is already choosen 'neo'. So I took ne0.
By the way, I can give merits to '0' which was invented in our country.
Greetings !!!
Ne0
mine just symbolizes who I am. I believe I am lost in the world and im a buff on tech so Lost_Signal kinda suits me.
