After the demise of the old Slacker, I wondered what would replace it on my podcast list. But Astronomy Cast is great, IMHO a big improvement on the original and far more interesting, informative and "listenable-to" than Slackerpedia (though it's early days, I guess). I like the format, the choice of subjects and the delivery. I hope Pam and Fraser enjoy making the program as much as I like listening to it!
