That with OT has been an eternal and livabde discussion on all sorts of forums I have been to. These are not natural laws we are talking about here. This is what those who decide on the forum's focus, policy, rules and so on choose it should be.Then take into account what Killdozzer wrote in the thread above. The complexity and how things can be connected. So what exactly is OT?
Then what is OT? Say a thread about sharing tips on making mussels in white wine. So are tips on oysters in white wine OT? Mussels in red wine? Suggest recipes for mussels with more lemon than than wine in the sauce? Suggestions for beef fillet and pepper sauce? Or in that thread tips on how to wash the car in the best way?
