I wrote a blog post yesterday about how my incoming podcasts list became overwhelming, so I tamed it using Google Reader.

Essentially, I use Google Reader to scan my “podcast inbox”, star only the ones I want to hear, and use that as my personal, filtered podcast in Canola on my N800.

Hope this helps someone!
