In many respects, the liquid limit is a classification test. It allows the engineer to classify the soil being tested within the context of the engineer's experience and also to published reference. What's the relavence of hardness if you don't have a way of knowing there are items that are softer and harder, for example?
Because it is mostly a classification type test, folks have made correlations between liquid limit and other soil properties.
Not to dispute what BigH said - just to add, that is; if the natural moisture content is greater than the liquid limit, it can also mean that the soil is underconsolidated, just as if the natural moisture content is below the liquid limit it can mean that the soil is preconsolidated. These terms help an engineer anticipate just how settlement sensitive a soil layer may be to newly-imposed loads.
It think it's commendable that you want to understand the testing that you are performing!
