Al Gore did not invent the PDF (nor, as I've pointed out before, did he ever claim to invent the Internet). But last week he did serve as keynote speaker at the CRE8 Conference, which used to be called the "Adobe Acrobat & PDF Conference," hosted by Aquent Graphics Institute, Aquent's official training arm.
As several commentators have pointed out, although former-almost-president Gore did speak engagingly about global warming and what we all could do to combat it, he did not talk about the role of the PDF in that battle. Nevertheless, he was, quite against character, apparently very funny (seen here yucking it up with the president of Aquent Consulting, Nina Eigerman who asked him to sign her Mac):
My man Al, he's taken the brunt of it for...forever. But now he has an Oscar and soon a peace prize.
Who's laughing now ;-)
