I may be in the minority on this one, but I want to hear your bio during a talk. To be sure, it's nice when they are short and sweet and devoid of meaningless accolades ("I was awarded CISO of the century in the 1900s by a print magazine, founded a made up not-for-profit that lasted five minutes, and wrote slam poetry and press releases as a teen member of a hacking group"), but I want to hear it.

I sit thru the equivalent of three or four security talks per day as an analyst. About the only thing really unique to you as a speaker I'm listening to, is your story (and sometimes hopefully your research or solution). There are a lot of voices competing for attention in infosec, and establishing credibility via experience out of the gate makes a difference.
