The Zend Framework team will be watching closely, since no fewer than two (!) new ZF-based projects have made it in to the finals: Magento and Tine 2.0.
Magento is a very popular eCommerce application that makes setting up an online shop quick and easy. It's well designed and has been nominates to several community spots like "Best Project for the Enterprise" and "Most Likely to Change the World".
Time 2.0 is focused on intranet collaboration and is a rewrite of the eGroupWare project (a collaboration suite allowing for instant access of any data from just about anywhere there's an internet connection).
You can cast your vote for these and other great community projects by logging in to SourceForge and selecting your favorites from the lists.
