Is 'cyber' actually used by technically competent folk now? It's been cropping up alot with the 'cyber' crime, 'cyber' attacks happening in 'cyber' space recently, needing improved 'cyber' security skills.
Usually the term's reserved for either mass-media outlets, or people trying to scare you.

It seems like cyber is generally used for online badness (cybercrime, cyberwar) while the e- prefix is used for online goodness (e-mail, e-sports, e-commerce)
I once kept a list of every cyber-* I heard at an industry conference with the idea of making Conference Cyberbingo. Notable entries included "cybertactics," "cyberstrategy," "cyberthreat".
For some reason, both of these terms make me grate my teeth!
I imagine it has something to do with only hearing "cyber" being used by people who are woefully out of date, and "Infomation Security" by people who are actually marketers that can use a computer...
The media has misused it so much, that much of the information security world (With the exception of pentesters from what I've seen) seems to have given up trying to use the proper terminology. They still seem to be trying to recover the term "hacker", though.
