In one of those great moments of serendipity, the most recent episode of the Guardian's Sounds Jewish podcast is about Jewish film, and contains a short funny rant on "Where are all the Jewish action heroes?"
"Aha!" I thought, as I listened to this. "I should share this podcast with the other members of the class! I'll send an email to..."
And then I stopped, remembering that this class doesn't have an email list.
Nor a blog, nor a wiki, nor a facebook page. Not even a yahoo group.
I think this is the first significant group endeavor I've taken part in in some time that didn't have some kind of internet channel for communication between the participants. It's slightly disorientating not to have it.
