Thanks Pavel
The changesets listed were reduced by half when providing the url
http://www.openstreetmap.org/browse/changesets?bbox=-73.6318%2C45.409%2C-73.444%2C45.4946
with http://positron96.appspot.com/osmfilter.html.
This solution would effectively eliminate an important amount of changesets
from the History Report if it was adopted.
Therefore, this solution does not cover all the situations. When a worldwide
changeset covers partly a local area, it is quite uneasy to detect wich objects
were modified in this local area. Especially when the changeset affects
hundreds of objects.
If changesets were limited to one country (or nearby countries when crossing
borders), there would be even less changesets reported in a local area.
Changesets would also contain less objects.
Both revising the History Report and establishing rule to restrict the coverage
area of changesets would facilitate monitoring in a local area.

shows all the changesets covering a local area. In this display, we often see
Worldwide
BOT Changesets even if there is no modifications made to the area,. RSS feeds
are producing false alerts, and it is uneasy to find if any changes are made to
the local area. We sometimes have to go to hundreds of modifications in the
Changeset to verify if the local area is affected.
