Hi, I don't know if this has been reported here or not.
A quick email to let you know that some time ago our own Cristian Consonni and Simone F. released a nice wikipeda to OpenStreetMap integration which is online at:
http://geodati.fmach.it/gfoss_geodata/osm/wtosm/index_2.html
it allows you to add coordinates to wikipedia articles and add wikipedia page links to OSM objects. Uses Catscan to find out which pages do require coordinates.
The tool is currently only available in italian. In the UI: "temi" reads "themes", and "regioni" reads "regions"
Thanks, Simone.
