Just noticed that there seems to be some odd issue going on with quotes in my last two episodes, which would appear to be an issue with smart quotes. It only seems to happen if you look at the episodes in firefox, and would seem to be due to character encoding issues. I write in LibreOffice, and in this case cut and pasted directly from there, which I think preserved the smart quotes and didn't convert them to the normal ASCII quote character.
Firefox seems to have long running issues with this, as is explained here:

for anyone who is interested.
Sorry about that. I'll try to stop it happening in future.
