I tend to write how I speak and attempt to create enough context so a casual reader on the topic can come away with something whilst still discussing the complexity for someone more versed in the subject.
I have written articles about identity theft, authentication over the phone, as well as other technology issues relevant to the public at large. [2]
I also write a weekly article about the hobby of amateur radio and have done so for over 13 years. It's published as an audio podcast, with email, video and Morse code versions. [4]
