weeklyOSM posts lots of interesting links. Here are some beautiful views of OpenStreetMap edits and renderings:
- OpenWhateverMap :: An Open Awsumnez Map: A quilt-like showcase of OpenStreetMap renderings
- Show Me The Way: shows ways as they are added to OpenStreetMap in (near) realtime
- OSM In Realtime: simple visualization of the changes made to OpenStreetMap in (near) real-time
- WHODIDIT: OpenStreetMap Changeset Analyzer which can also generate an RSS feed for an area, so one can stay on top of what happens to the bits of the map one cares about
