Mod note: Split from Reminder about keeping threads on topic: Reply as linked topic
It seems like the very slightest change from what is suppose to be the topic is frowned upon and gets moved…
But this is the way people communicate, discussions evolve. I run several forums, and we decided to be pragmatic about off topic posts. Leave in place one or two but only split off when that one or two does actually become a an obvious whole new self contained discussion. Otherwise we let it be and generally the OT posts go nowhere, or they go off at a very slight tangent that is still useful to the original topic and often come right back to it.
We also have an off topic bbcode, so if somebody wants to make a single off topic comment within an on topic posts, or one that is just a one-off but triggered by something in the thread, then they can mark as off topic. At one stage I think these were formatted as a spoiler but now we just have an OT prefix the the specific OT text within the post or thread.
It took us many years to end up at this system, learning the hard way by getting disgruntled members complaining about too many split off threads which inevitably often seem to come from nowehere as the original OT post isn’t always written well as a thread starter
