[Cryptography] people who don't understand how to use search engines

[Bob Wilson]

I think a large part of the problem is the growing percentage of users 
who got into the internet and the web via some "simplified" front end 
rather than the UNIX world. If you have never heard of "regular 
expressions" you probably won't see the patterns in what you can ask 
about, hence never use them consciously. C shell, Bourne shell, 
whatever, in "the good old days" there were clear statements about what 
you could do, and learning them led to a lot of power over the 
environment. And I'll also throw in a good word for the "man" command 
that let us use things like that even when we did not remember every 
detail.
