Personally I prefer to take GPS tagged photographs when trying to pinpoint something outside. However, this method doesn't (reliably) work everywhere (e.g. in urban canyons).

I assume everybody saw my talk yesterday :-). Seriously, even if you don't expose geometry to the end user your editor needs to be geometry-aware (that means have at least internal access to all variants of how the object of interest can be modeled in OSM) and make the user aware of the presence o
