Canada's public radio network is launching two podcasts:

/Nerd: Tod Maffin's weekly technology column
Quirks and Quarks: Weekly award-winning science show

Judging from the format, their target audience is geared towards tech savvy web audio users. You'll find a more blog-like appearance at /Nerd while Quirks and Quarks requires some searching before stumbling into the mp3 files.
