Love open source, free software, stackoverflow and any concept which allows people to share knowledge and information.
Convicted Plonista since 2007, as it shows to be continuously the most secure open source CMS, which is probably also due to the fact, that no PHP is involved and the object-orientated data-management (Python rules!), besides of the genious work of the ZOPE/Plone-founders.
End of 2013 the German Federal Office For Information Security published the results of their study towards potential security-risks in CMS'ses and came to the conclusion that Plone (the most popular CMS built on top of ZOPE) slighty tops the other compared PHP-based CMS'ses (Drupal, Joomla, TYPO3 and WordPress).
For german speaking folks, this excellent write-up of Armin Stroß-Radschinski might be interesting: http://www.plone.de/nachrichten/plone-hervorragend-in-cms-security-studie-des-bsi
