That depends on the application. If you are talking about using it as a 
voltage divider, you only need to be considered about the loading 
effects of whatever resistance is hanging off it. If you want it to act 
like an audio taper, you can purposely put an "excessive" load on it. If 
it's going to be used as a gain element in an opamp feedback loop, you 
can change the other gain setting resistor and still get the same gain.
Here's an article on pot substitution:
