IMHO big human settlements are more difficult than small ones when it comes
to define their edges. You can represent (from a data model point of view)
every place as an area in OSM, nodes are a somehow preliminary solution
(and good to indicate a central point which might often not be the
geometrical center).

shops can also be represented by areas (see above, preliminary), and a lot
of people already do it (see http://taginfo.openstreetmap.org/keys/shop )

a node isn't a nice representation of a geographical region, as it doesn't
convey information about topology (region inside region, boundaries between
regions etc.).
