Hey, I've been a dedicated watcher for some time now and I've kept myself informed of the episodes via iTunes podcasts-system.
Anyhow, last time I didn't remember to close the Last.fm client, info went straight to the Last.fm site. It seems I'm not the only one who's done that.
I'm babbling, here's the link.

I also noticed that Hak5 didn't have it's own group in Last.fm;

Now it has. Come and join up! :)
