Thousands of years ago I did Speechification with Steve Bowbrick and Roo Reynolds. It was a podcast of interesting speech radio. Other people's radio. We didn't own the rights but it was the days when no one even understood what we were doing so it didn't seem to matter. Then, slowly it started to matter and we got scared and stopped. But people loved it because 'discovery' for interesting bits of radio is hard. It's still hard.
The twitter account still sits there. I'm not sure who has the login details. The links have all broken. And there's a tumblr from a point when we tried to make it into a 'curation' of Radio 4 rather than a pure rip-off, so a lot of those links still work. There was a Facebook group too, I occasionally get a notification about that.
It's still an itch I want to scratch so I've started 41256. A similar thing but with fragments of audio, not whole programmes. It's less than 5 minutes long, that seems an under-explored podcast length. You can subscribe via iTunes or find it on Soundcloud. Let's see how long this lasts before I get scared.
(There are currently 404 of you. Brilliant! The most famous error message. According to wikipedia - "In 2008, a study carried out by the telecommunications arm of the Royal Mail found that '404' became a slang synonym for 'clueless' in the UK." I think that's not true.)
