I don't know if I should feel pleased to be recommended as the first port of call for OSM wreckage of any kind ;-) here's a few tips how such a situation could be investigated. If you know the date, then you can download the daily change file, in this case http://planet.openstreetmap.org/daily/20100207-20100208.osc.gz and either work on that with plain old grep, or use the slightly more comfortable oscgrep.pl (from /svn.openstreetmap.org/applications/utils/filter/oscgrep) which lets you do this: perl oscgrep.pl -a modify -r 'user="neufeind".*different' 20100207-20100208.osc.gz to find all objects which user "neufeind" modified and tagged with something that included "different". In this case we find that you have tagged 2201 objects with "bridge=<different>" (and no other ...=different). Strangely, 2152 of them are nodes, and only 49 are ways. All this happened in changeset 3818805. I started the process of reverting those changes, but of course this will revert objects to their old and also broken state. (Many of the 2152 nodes probably shouldn't have the bridge tag at all - perhaps, rather than a wholesale replacement, these should be checked individually.) But you are not alone, there are 364 "bicycle=<different>", 174 "building=<different>", 241 "highway=<different>", 343 "lanes=<different>", 1138 "waterway=<different>" and a lot of other things as well. I particularly like the 19 occurrences of "source=<different>;extrapolation from DOP" which show that automatic concatenation of tag values with a semicolon is perhaps not ideal.
