Where do you search for jobs?

This is a question a friend of mine has been closely researching recently - more specifically: Where do you search for Software Executive jobs [Sr Dir/VP-level] at small-to-midsize and larger companies?

His answer so far: Monster (good), LinkedIn (ok), CareerBuilder and CraigsList (poor). YMMV.

I realize this doesn't exactly fit the startup context at HN. I apologize if it's considered off-topic, but I thought it might be of interest for some.
