Line Pilots and FARs

[Guest Stompy]

Hi! What is a Line Pilot, and how are they different from other pilots? Along the same lines, what's a line technician or line guy? I think I'm missing a piece of terminology here, and I'd like clarification so I can sound like I know what I'm talking about. :-) Are FARs something you refer to as a reference, or do you read them from cover to cover? Thanks!*edit* Just realized my subject line looked stoopid. I was trying to say "About Line Pilots...", not On-Line pilots.
