Diggnation: An overview of what's popular on for the week. And the hosts drink while reading. Beer spills a plenty. Co-Starring Kevin Rose, a TechTV vet.

GeekBrief.TV: A quick look at a pretty gadget or two.

WebbAlert: Morgan Webb just summarizes what is popular on the web lately. She is on my remove list for doing advertisements without claiming it is first(or having a fadeout or something to note the flow has changed). She is new to podcasting, so I'm trying to be nice.

TEDTalks: Feel like getting a little smarter? TED is here to help. Smart people talking about interesting stuff.

EPIC-FU: More web review. Just what's hot on the web.

Tekzilla: About 30 minute if technology news. Some of you might recognize Patrick Norton the Tech TV of old, or that Street View the Google Maps van snapped of him.

Science Channel Video: A mix of extra information from the Science Channel. Things that don't make it on the air.

Experiment of the Week: A quick little experiment involving something you mess with everyday. Watch this a bit and you will start wondering how everything works.

Discovery Channel Video Podcast: Extra scenes from normal Discovery shows. See behinds the scenes at Mythbusters, Man vs Wild, Future Weapons, and more.

Channel Frederator: Grownups can enjoy cartoons too! The Frederator is here to bring us cartoons by the average man. Don't expect episodes of the same cartoons over and over again, but rather something new from someone new every episode.

Ask A Ninja: We all have questions for Ninjas, but it's hard to flag one down. Ask A Ninja Ninja is here to help. Here's my question: Why are pirates so much better than ninjas?

Boing Boing TV: Random stuff. Who knows what they will play next. Good for a laugh.

Onion News Network: Fake news that is serious business. You will laugh at every episode of this. More tech news from more of the old TechTV gang.

Cranky Geeks: Just as the name suggests, it's geeks being cranky about stuff. It's nice to hear people who aren't afraid get bitchy about tech.

I opted out of mentioning a few that I don't much like, but some people might. If you wish to view any of these podcasts, I recommend Miro as a great video podcast player.
Another good podcast is Distorted View.
I wouldn't call that well rounded as much as I'd call it linear. All of that centers around science and technology.
