I listen to the following:
Tech:
Android Central Podcast: I'm a big phone nerd + I use an Android phone.
Buzz Out Loud: I kinda fell off the bandwagon on this one. I loved the unique mix of humor and tech news the original hosts had, but now that two of the three left for TWiT, they've changed the format of it..I need to catch up on it tbh.
CrackBerry.com Podcast: I mostly listen to this for news about the BlackBerry PlayBook tablet.
Dialed In: A general cell phone podcast, it's pretty good stuff.
Engadget Podcast: One of the best general tech podcasts around...very funny as well.
Engadget Mobile Podcast: Pretty much the same as the regular Engadget Podcast, but strictly about cell phones, with two Mobile specific hosts.
MacBreak Weekly: It's weird that I listen to this, because I don't own any Apple products, but I've always been able to use Mac OS well, so I listen for that and other news
The 404: Hmm how best to describe this one...it's kinda a tech/pop culture mashup with very funny stuff and guests.
This Week in Tech: I like this podcast because it has a "roundtable" like feel to it and people aren't afraid to say what they think about serious tech issues, or the fun stuff either
Windows Weekly: Very good podcast about many Microsoft topics, not just Windows
Automotive:
Autoblog: I know they seem to be loved or hated, but the podcast is great. The hosts know what they're talking about, always have fun doing it, and are opinionated and not afraid to call something that's crap, crap.
Do you happen to know any other car podcasts that are like Autoblog? I know there's probably plenty of niche/offbeat stuff but idk..
There's a few more podcast feed i have in the RSS reader, but I don't listen to those anymore...should prob delete them
