Steve said: "If you know that you have a user segment that is relatively scarce, but important for you to capture - like your executive team, for example - you should be certain to include a representative of this group in your studies. Essentially you're adopting a stratified sampling technique rather than a purely random sample as a deliberate tactic to cover small audience groups."
Just make sure you take this into account when you evaluate any of your findings quantitatively. Your small audience groups would be over-represented in this case.
