Recently I have noticed that threads in critique forum have been sometimes hijacked into lengthy discussions about the relative merits of the subject matter rather than the piece of work itself.
Now although it's sometimes relevant to the sketch it frequently detracts and puts others off either leaving a comment or else being bothered to read the actual sketch. The writers' discussion forum exists for this kind of thing surely. I think we should try and keep this activity to a minimum.
Then we have other petty squabbles that also put people off and that are very frustrating. Bad enough if it's on their own threads but when they hijack someone else's thread to keep it going it really is ingnorant in the extreme. Take it outside kids why dontcha?
But worst thing of all is people who take it on themselves to do a total rewrite of somebody else's sketch.
Apart from it being fu**ing bad mannered it is rather, in most cases, unnecessary, almost always missing the point of the sketch by a mile as they don't know what the originator of the work had in mind. It also frequently prompts their claque to pitch in with "yeah that's a whole lot better!
Sure, the odd time a suggested re-write is appropriate but only when the originator actually asks for it, otherwise I think it is bad netiquette in the extreme.
People put their work up for comment if you want to talk about something else don't post on their threads. Start a new one in Discussion 
I've said my two penn'orth and now I'll shut up
