lat/lon coordinates aren't an ideal solution for this. Imagine some live rendering (using JavaScript, Flash or whatever). The programmer wants to add the following features: - different color for buildings with Wikipedia article - mouseover highlighting of buildings - clicking on highlighted building opens Wikipedia article Can the programmer do that with lat/lon? No. Because lat/lon doesn't offer a connection between an article and a certain OSM primitive. Similarly, in a map with icons for POIs, you will need to add additional icons for Wikipedia links, so you will end up with two icons for the same POI. And so on. So what can we do to store that connection? We can - link to a Wikipedia article from OSM -> does work, but of course this causes a "notability" problem if links to other sites are added, too - link to an OSM id from Wikipedia -> ids are probably too fragile - invent some new way of adressing OSM objects; for example: lat/lon + tag(s) that will be looked up in some region area around the lat/lon ("The pub with name=Foo near that location") -> could be a rather robust solution, but doesn't exist right now Therefore, I can understand very well why people are adding wikipedia=* tags. It might cause problems later, but the other solutions have apparent flaws right now.
