Aye, I pretty much grew up with the Listener and it definitely went well downhill in my last few years of reading it.

Interestingly, the conservative swing pretty much exactly coincided with my parents' post-50 conservative swing (they're still Labour supporters, but a lot more angsty about things like crime than they once were, as seems to be common in their age group). I almost wonder if they were intentionally trying to move with an aging audience.
