Yes, I have. As far as I know the word was not there before Gibson coined it, so I'm assuming that everyone using it today refer back to that, whether they know it or not.
I haven't been around in the English-languaged internet back then, so I don't have firsthand information, but it seems to have been more commonly in use everywhere in the past (I remember some hacker's handbook telling me not to associate with people calling themselves 'cyberpunk', for instance). Nowadays the only mentions I see are from governments who plan taskforces to anwer "threats in the cyberspace", which, in my eyes, makes them look incompetent. I think it's interesting that they use that terminology though. </rant>
'Cyber taskforce'? And you want me to take that serious?
