Denver has a very vibrant meetup community.  I have reconnected with old friends, and met new friends, at the Java, PHP, HTML5, Joomla, Wordpress, Android, GDG, VR, and other meetups around town.  There are so many groups, that sometimes there are scheduling conflicts for people like me, who have a broad range of interests.
