Fuel Filter Replacement - How Often?

How often do you replace your fuel filter and what do you use as an indicator that it's time to replace it?

I installed a fuel pressure gauge after the fuel filter as an indicator to when I need to change it out, but I don't know how fast the filter will plug or if there are other issues that could come up by not changing every x miles. So far I have about 10k miles on my filter and my fuel pressure has not changed (~10 psi).
