Better yet, work a few highlights into This Week in Tech and Tech News Today.
Not a cumbersome amount...just very small, appropriate, newsworthy segments.
In this model, we would have This Week in Tech as the flagship weekly show, and TNT as the daily version of this, an within these two general-interest (general-interest for the tech enthusiast) shows, you will include highlights from your other network shows.
This way, people will pick up on other shows that they might like, and decide whether to add that podcast to their listening list. If they enjoy the show, they might even become live listeners! (More about live listeners in a later post.)
Interested in science? Maybe you hear a clip from Dr. Kiki's show during TNT, and decide to add that to your schedule? Maybe you are more interested in Security issues? I think we can all agree that this is a very important and topical issue...so why not play a short video of Gibson explaining something about it?
I know that the TNT crew is computer-savvy enough to explain security issues themselves. It's not about having a more qualified commentator.
It's about promoting the more specialized shows.
It's about letting your audience know what else you offer.
We want them saying to themselves "Hmm...maybe I should check out that show about...."
So mention All About Android, just have Howell refer to his show during TNT. He's already right there, and 500,000 more people activate android every day! Get in front of that!
Let people know where they can go for more in depth coverage. Same goes for NSFW, or the Computer Hardware show, or that show where they rate the frames, or even that one about Chipotle, or the radio tech show, etc...
Hook them into TWiT and TNT, and let your general-interest audience filter down into their specific niches.
There are weeks when I just don't have time to listen to all the TWiT shows I would like, so it would be a great service to me to be able to see a highlight reel now and then. You have some real experts working on these shows, and if I don't have time to watch every show, I at least want to feel like I'm keeping up with them.
I would wager that many of your listeners are similarly busy/productive.
And by the way...during your podcast, always mention what time the show is LIVE. If someone really enjoys the show, that is where they may want to go next. The live show and chat room is a completely different experience.
