This is the day I've been waiting for! It seems like years I've had to manually check their website every week or two to look for any new episodes.
Now their RSS feed works properly so my computer can do the work for me.
Are We Alone is one of my favourite radio shows/webcasts, its produced by the SETI Institute. Although there are times when I wish it was more dry like all the other science/sceptical podcasts I listen to, but this also gets broadcast as an actual radio program and so it has a much lighter feel to it.
