Dr Dunlop is always going on about this; she was very sharp with me on another thread when I was (allegedly) guilty of this faux pas. Perhaps she could advise where oiks like me can educate themselves about what is and is not good form in 'the world of the interwebs'?

In defence of 'hijacking':

1. it's fun

2. it's not really hijacking anyway, because facetious etc interventions can always be ignored by those who want forum discussions to be conducted with the rigor of an academic seminar

3. if the worst comes to the worst, 'admin' can always transfer the offending posts to a new thread, where bad boys can continue to have their fun.
