PyPI usage statistics, the zc.buildout effect
by Tarek Ziadé
It is interesting to look at the usage statistics at PyPI: http://pypi.python.org/webstats/usage_200805.html#DAYSTATS
Besides the front page, the most visited pages are in order (same thing in April):
Then the packages in the top 60 are mainly zope eggs. This corresponds to the sequence done by a Plone or Zope being build in a buildout.
If you take a closer look at http://pypi.python.org/webstats/url_200804.html, the next top hits corresponds to zope.* then plone.* packages.
