My crusty old dictionary says: "A formal discourse on a topic," and since the topic was a BBC News screw up in August, we should be talking about that, surely?
I don't think there's any point in leaving this topic open, since I doubt there can be much constructive discussion about a relatively minor event which happened five months ago.
In future, try to remember to create a new thread rather than bring something out of that black hole which threads disappear into. It's OK if it's about a month old or less, but something nearly half a year old should really be confined to the dustbin of history.
