I had a great time working the Joomla! booth at ZendCon - The Global PHP Conference at the Hard Rock in Las Vegas this last week. It was exciting to talk with developers about the trends and the upcoming features and enhancements in PHP7 and MySQL 5.7. The conference was a good opportunity to meet other Joomla! users that I don't normally see at the JoomlaDays, as well as, introduce some people to Joomla! and encourage more people to join the community.
The conference itself was full of great sessions and was well organized. The sponsor booths also has challenges to earn your shirt and PHP7 elephants, so it made the booth area much more interactive.
