Apparently I’m an old fart, because I can’t figure out how to listen to them, but Permafrog  aka Growing Green’s  is podcasting along our lines (the rumor has it), with things like reviews of Food Not Lawns  and The Relolution Will Not Be Microwaved , among other things. Permafrog’s older casts seem to be available as .wav downloads. Maybe you already have to be subscribed to get the more recent ones delivered to you? A little patience and maybe the December casts will become downloadable too.
On the radio last night I heard about a survey of kids and internet stuff, and the young tykes nowadays think of email as an aged, old skool technology. They use chat/IM and text messaging almost to exclusion. It’s a brave new world. I expect something new will come along and make instant messaging obsolete by–what do you think–August? Where’s a little good old fashioned ESP when you need it.
