Yes, it is almost 2012.
Looking back for overlooked content I'm compelled to mention the 2011 annual "LDAPCon" conference focused on directory services and LDAP; the organizers/hosts have made available some excellent videos and papers [index page]. These are an unrivaled source of information on the current state and future of directory services.
The same is also true of the annual SambaXP conference in relation to all things Samba and CIFS [2011 content index].
Podcast content in general tends to be lite and aimless fare; those sources provide some meat for the meal.
