There's always been a debate about what is and isn't acceptable on TV news programmes, and now that we have blogs, forums and podcasts it's only getting more complicated. And should Newsnight's on-line persona be exactly the same as that on TV? Here are a few of this week's posers.
• Our Ethical Man Justin Rowlatt caused a degree of outrage when, in a film about cycling proficiency (watch it here), he asked a youngster if he was "pissed off". By today's standards that's hardly obscene and I'm sure the minor in question had heard, and probably said, much worse, but I must admit I spluttered into my cocoa watching at home.
On the other hand, when I used the term "crap prizes" in a response on this blog, I was surprised that some viewers thought that was inappropriate language for the editor of Newsnight, even in an obscure corner of the blogosphere.
• A few of you have been writing on the blog complaining that some of your comments have been censored and asking why. In short, I don't know. On Newsnight, we censor nothing that appears on the site, but we do employ an outside moderating company who check for, among other things, "profane, abusive or threatening language" (full guidelines here).
So, in response to a question about graffiti scrawled on his abandoned car, the foul-mouthed Justin's strictly factual response was barred from publication. I'm not going to repeat it here, but it begins with "w".
• Where does informality end and falling standards begin? Yesterday on the website, we asked you - as a diverting pastime while we waited for Mr Blair - to construct a statement which might get the PM off the hook. About 300 hundred of you obliged, but one bridled: "I find this exercise pretty stupid for the level that BBC and Newsnight traditionally were holding and still claim to hold."
• I enjoyed the fact that when Laura Kuenssberg said that Jack Straw had been talking in the past tense some of you pulled her up, pointing out he was actually talking in the present perfect (the operative phrase was "has been"). Then again - as some of you have also raised - the standard of spelling and grammar among viewers' contributions to the blog is sometimes pretty appalling. Not what we would expect from Newsnight viewers.
• Two quick ones which raised eyebrows inside and outside the programme. Tony Blair portrayed as Christ at the Last Supper as an illustration of that memo. Blasphemy or genius? And what about Kirsty's description of Gordon Brown's command and control network as Al-Qaeda-like? One of our own programme editors thought that was appalling.
