I’d like to propose a word:
eKnow: To know someone through online interaction only, often having never met the person physically, but feeling a close relationship to that person.
For instance:
"Do you eKnow Mr. Smith? I’d love to have you introduce us via email."
As we move forward socially as a society, I think this will be a more and more significant interaction. People we’re close to may not be in our physical presence.
