You might be asked if by Computer Science you mean what used to be known in some places as Computing Science, which also falls into Programming as in http://www.reddit.com/r/programming

See for example:

or, instead, you mean the generic Information Technology mumbo jumbo. No bias here ;-)

I am looking for more the theory side of Computer Science. For the programming aspect I definitely look here first and then /r/programming.
