Ask HN: How do you manage server ssh fingerprints?

I am curious how people manage the ssh server fingerprints in a way that is practical and secure. In the past I have tried emailing my team members the fingerprints but I have no way of knowing if they check them. I have also tried monekysphere but it slows things down too much when establishing a connection. Are there alternatives?

I am aware of using certificates instead of keys but I am specifically interested in using keys.
