Conversations naturally take twists and turns and on message boards it is not the exception. But there is a fine line between going from blue to green and going from WHITE to BLACK.
I don't see small hijacks and posts mildly deviating from the OT as a problem. Hypothetical-but if the thread is about relationships and someone suddenly posts about cars and the thread goes on about cars several pages long, that is just disrespectful-to the original thread starter and the people who want to discuss the original topic. All of us has done it time to time, but there are some guilty people who do this ALL the time and I seriously think this is done on purpose.
In certain forums this wouldn't even be allowed.
*edited* I am warning you: If you hijack this thread I will FOREVER hijack yours. Agree?
