Of course. Nearly all other mapping sites/software does this as well.
Here is a quick example of MapPoint directional street mapping. The advantage being one does not have to plan a trip over such to learn which in which direction a given street (or collection of streets) travel. The example used in the city is a case where it wouldn't really matter (as the streets are very grid-like), but there are cases where it does, of course - Queens comes to mind,. Also, MapPoint can add reference landmarks by default, if desired (subway/transportation stations, museums, stores, etc).
Not discounting Google at all. I hope to make use of Google as well. Just unfortunately lacks some functionality that may or may not be added as a part of the Beta (likely not).
Again, for free access (MapPoint costs, of course - in general), Google seems better than most of the other options.
