According to Infoworld,
"If the likes of WordPress and Movable Type are too simple or closed-ended, consider Plone, an industrial-strength content management system built on top of the Zope application server and the Python programming language. In addition to blogging and page/asset management, Plone includes events and calendaring, user accounts and discussions, and integration with directory services. Dashboard views can be based on user-group membership, to customize internal views based on department, for instance. Plone is also up-to-date with modern Web standards (HTML5, jQuery, and so on). Additional functionality comes through a whole galaxy of extensions sold or provided by third parties."
And if that wasn't enough, PC World picked Plone out of the many winners of the Bossies in an article which highlighted "Ten Open Source Apps to Try Today"
This is great recognition for the Plone project and all the users, developers and integrators who make up the Plone community. Congratulations.
