I have a feeling the suggestion that Anthony was referring to was one I made. It came up in the context of mapping architects, lawyers and other professional bodies. There comes a point where they're not really POIs or "amenities" any more, but simply a business directory. Which I think would be handled much better by having an actual directory, and georeferencing back to OSM in order to render a map, or load data onto a GPS or whatever. I'm not advocating using the directory instead of amenity=cafe or amenity=fuel or whatever. But in the long term, the ideal solution would probably be to allow that directory type information to be maintained separately, in a more convenient form than a 2D map. Particularly since while addresses are relatively fixed, their contents changes. (Around here, it seems that every time I walk down the main street, there are cafés I haven't noticed before - some tenancies last less than six months). And some kind of solution like that is needed to cope with multi-storey blocks of offices anyway, I think.
