Dvorak was on the start-up team for
CNET Networks, appearing on the
television show CNET Central. He also
hosted a
radio show called
Real Computing, and later 'Technically Speaking' on
NPR, as well as a television show on
TechTV (formerly ZDTV) called
Silicon Spin. Dvorak helped develop the game
Dvorak On Typing. He appeared on
Marketwatch TV and
This Week in Tech, a
podcast audio and now video program hosted by
Leo Laporte and featuring other former
TechTV personalities such as Patrick Norton,
Kevin Rose, and Robert Heron. Dvorak was once banned from the show. In March 2006, he started a new show called
CrankyGeeks, where he led a rotating panel of "cranky" tech gurus in discussions of technology news stories of the week. The last episode (No. 237) aired on September 22, 2010. In 2007, Mevio hired Dvorak as vice president and Managing Editor for a new Mevio TECH channel, where he manages content from existing Mevio tech programming. He also hosted the show "Tech5", where he discussed the day's tech news in approximately five minutes; it ended production in late 2010. He co-hosts a podcast with Mevio co-founder
Adam Curry called
No Agenda. The show is a conversation about the week's news, happenings in the lives of the hosts and their families, and restaurant reviews from the dinners Dvorak and Curry have together when they are in the same city (usually San Francisco). Curry usually has more outlandish opinions of the week's news or world events, while Dvorak plays the
straight man in the dialogue. Since early 2011, Dvorak has been one of the featured "CoolHotNot Tech Xperts," along with
Chris Pirillo,
Jim Louderback,
Dave Graveline,
Robin Raskin, Dave Whittle, Steve Bass, and Cheryl Currid, at CoolHotNot's web site, He shares his "Loved List" of favorite consumer electronics, his "Wanted List" of tech products he'd like to try, and his "Letdown List" of tech products he found disappointing. Dvorak hosted the show
X3, which, like the defunct
Tech 5, was a short tech-focused cast. Unlike
Tech 5, it was in video format, with two co-hosts. The last update was 24 June 2012. Since September 2009, Dvorak has hosted the
DH Unplugged podcast with personal money manager Andrew Horowitz. He is a co-founder, with
Gina Smith and the late
Jerry Pournelle, of the web site aNewDomain.net, where he is also a columnist. In September 2015,
Leo Laporte infamously "banned" Dvorak—his long-time friend and frequent guest—from
TWiT for comments Dvorak made on Twitter. In reply to Dvorak's comments that Laporte was biased, Laporte told Dvorak "you won't ever have to worry about it again", ==Criticism of new technology==
