DKIM is not that well (or much at all) supported on a planetary scale.
SPF however is important, but I guess for GTALUG, you say 66% of us DROP
based on DKIM? 

That is so weird, that so many little email service providers would be 
choosing to LOSE valid emails from the rest of the planet... *sigh* 

I guess this means 66% of the people on the list lose real and valid
emails daily, this is scary...
