Within limits, I tend to feed leaks. If you have a few drips on the ground after you've run the car, or after it's sat overnight, I don't sweat it. If you have a fresh puddle, like an ounce or two, I'd start to worry.
An oil leak is a problem IF you can't keep up with it, or it's the sign of a major problem. If you need to add a half-quart every couple of weeks, feed it - it's not worth fixing. If you have to stop the car every hour to add a quart of oil, then fix the leak.
If the leak seems to be getting worse, then you have to worry about when something major might happen, like a main seal blowing. That happens, and you could lose engine oil quickly.
Just as a suggestion, check the one-way valve in the hose between the valve cover and the intake manifold. This hose pulls oil vapors from the crankcase into the intake to be burned. If the valve fails open or is missing, under boost the pressure can pressurize the crankcase, which stresses seals. If the valve sticks shut, the crankcase can pressurize itself, also stressing seals.
