OpenStreetMap
The new history tab is very interesting, however, I've spotted something that makes it a lot less useful: Changesets that cover huge geographical areas. I'm not sure how these come about, but I have seen a changeset with one point POI in Germany and one in the USA. Perhaps these are the work of bots.
The problem is that such a changeset is listed under the history of all locations within the box defined by these two points. For an area where few recent changes have been made, the history is totally swamped by just a few of these wide area changesets.
Perhaps the system needs to filter out changesets with a very large areas.
update: I noticed this has been added to: http://wiki.openstreetmap.org/wiki/OSM_Protocol_Version_0.6/Known_problems
Lets hope this gets worked out somehow soon.

I guess the editing was done with Potlatch? Not by robot?
Used have to use key "c" to close the changeset and start a new one.
Or stop working for at least one hour.

ah - I hadn't figured out how Potlatch would handle sessions. I guess you're right - it's people making two seperate edits in different parts of the world within an hour. Maybe there needs to be some logic that says "this is too far away to be considered the same changeset" or something?
