I do have a suggestion about the level of debate, and, alarmingly, it's GC's intervention that led me to think of it.
I'm not suggesting that it's a rule, but more of a guideline. 'Read the thread before you post'. As in don't simply react to the last two or three posts, which may be a repeat of an earlier thought, or simply a diversion.
Now I admit to having deliberately diverted threads in the past (in fact I would claim to be an expert at it) but it is a bit off-putting when people divert the thread without thinking about it, when, perhaps, they might have started a new thread. And, likewise, it is a bit tedious reading through posts that simply re-iterate what has been said before, and, oftentimes, less clearly.
There, GC, your work is done........(shame about the blog, by the way)
