There are many uses for that. In general, this way you can make
gradual transitions between two layers.
For example, a typical sunset photo has a sky that looks OK, but the
ground/water is a bit too dark.
You can duplicate the original layer, then raise brightness of one of
the layers, then combine them via a layer mask, where selection
gradually changes. As the result, both sky and ground/water will look
just like when you were taking the picture.
Here is another example of, ahem, artistic use of this feature:
