Blogging about your own presentations is tough. Some people post their slides, but slides are not essays, and often make little sense without the speaker.
I really like what Chris Hoff did in his blog post, “Security and Disruptive Innovation Part I: The Setup.”
I did something similar after “Security Breaches Are Good for You: My Shmoocon talk.” I posted a PDF of the slides. I think the PDF is less effective, because you can’t skim it, search it, or excerpt it as easily as with Hoff’s HTML version.
Nice work, Chris!
