[OSM-newbies] Tagging POI's: Draw buildings, add points, or both?

[Kenneth Pardue]

Now that the Bing imagery is available, it's much easier to see and draw the outlines of buildings.  I think it looks really nice in my home town to have the building shapes available on the map.  But with regards to applications that use the data for routing and searching, is it better to tag the information in the building shape, to drop a point on the map, or to draw a shape, tag it as "building" with no other information and then drop a point on top of it where the information about the business is included?

Or, am I completely off base by drawing the buildings at all?
