Mike, Firstly, I think Tom Chance has covered all the significant issues.
I'm assuming that the types of assets your potential users are interested in are of the order of schools, libraries, health facilities etc. rather than street furniture. In these categories I would estimate a typical level of coverage in OSM will be between 30-50%. With open data there is scope to improve coverage in many of these areas. However such POIs are likely to be mapped in diverse ways: from a single point for a school to a polygon for the school grounds with buildings, staff parking, playgrounds and playing fields all mapped, In initially presenting information it will probably best to abstract things to a single representation (e.g., polygon centroids). A related problem is of duplication: a school polygon with a separate node containing the school name. Again some kind of pre-processing of the data for specific assets may be useful. The potential complexity of the underlying representation may create problems. Tom has covered this in his point 2.
