Just a comment not all the data is the map database is presented on these
map renders.  I've been using Maperitive to selectively select data to be
displayed for a particular purpose and working with the rule set to display
the information in the way I wish it to be displayed.  Working with a local
copy of the database gives you a lot more control over the display options
including what is displayed and how it is displayed at different zoom

OpenStreetMap and its tools do have a learning curve but they are very
powerful.  It's interesting to note that it is possible to use the tool set
and environment to create private maps where cc-by-sa is not available for
one reason or another.
