psst..she spelled vigorous wrong! Here's the anectode behind the domain name:
vig·or·ous: possessing vigor : full of physical or mental strength or active force
ten·den·cy: a proneness to a particular kind of thought or action
Viggo Mortensen: A man who not only has handsome looks--but a sheer genuis persona. The brilliance of his poetry and the remarkable magnitude of his photography and art. He is a man of mystery and that acts like a narcotic on people who chase what they cannot have. He gives immeasurable depth to his work with full commitment and full conviction.
Thus, a proneness to all that is Viggo.
