Currently, OSM wiki URLs are quite long by default. However, there are two ways of shortening them: Replacing the openstreetmap.org domain with osm.org, and leaving out the “wiki/” before the article name. So for example http://wiki.openstreetmap.org/wiki/JOSM can become http://wiki.osm.org/JOSM.
It is clear that we are using openstreetmap.org as our primary domain, so the osm.org would only be used in case of space constraints, e.g. on Twitter. But what I don’t understand is why the “wiki/” is in the URLs at all. It doesn’t seem to serve any useful purpose as the wiki already has its own subdomain.
So, what I’d like to discuss here: Do you agree that using URLs like http://wiki.openstreetmap.org/JOSM would be better than the current wiki URLs? And what are the technical problems, if any, preventing us from implementing this?
