On the sprint there\u00a0were nearly 20 people who use Zope for their daily work. Some of them even joined the sprint without the backup of a company in their spare time. Yes, it will need time and effort to keep Zope alive and make it prosper in the Python 3 wonderland, but Zope\u00a0is still needed and has its place in the audience of web frameworks.<\/p>\n<p>We at gocept will keep Zope as part of our supported technology stack in the projects it fits the purpose and will offer help to others who need to migrate a long term project into the future. We will be at the <a href=\"http:\/\/www.pymunich.com\/\" target=\"_blank\">PyConDE in Munich<\/a> at the end of October and will be open for questions and further discussions.
