What are the recruiting conferences you attend?
Staffing World in San Diego
Sourcing Summit Europe
I really like the concept of "HR Unconferences" (have attended 1xBerlin and 2xBratislava, but they're all over the world). Unlike most conferences, these feel more like discussions among friends and the atmosphere really helps getting to what counts most: know-how and connections.
