Wizzy Wig is a phonetic spelling of the term "WYSIWYG" which stands for What You See Is What You Get. It's a common term people use when talking about web editors.
I picked it because it represents our business ethic. We are down-to-earth, honest and when you deal with us, what you see is what you will get. I won't sell you something I can't deliver, I am transparent in my dealings with you, and in general, I tell it like it is.
The other reason is because it just sounds cool. We try not to take ourselves too seriously around here.
