I've read several of the cable threads. First of all with interest, then amusement, consternation, and eventually despair. I've always opted to refrain from joining the fray, mainly because everyone is in full attack mode by the time I happen accross a cable thread and all the useful debate has ended.
However I think that the level of debate just reinforces that these are areas of discussion with a lot of variety of opinion and a wide range of objective and subjective factors to debate and arguably these are the ones that need and naturally prompt the most discussion. Most people can be trusted to voice their opinions and convey their knowledge (or in some cases "knowledge") responsibly and respectfully and they tend to vacate the discussion when it all goes south. I think it's pretty obvious to most posters that by page 3 or 4 the useful contributions have generally ended and the mud-slinging has started.
So I say continue broadly as is, but with tighter scrutiny and regulation of any posters who stray into agressiveness or offence.
Incidentally idc, I know this was done out of the best of intentions, and hence I have given a sensible response. However if this thread doesn't somehow end up going horribly wrong and ending up in a fight about whether or not cables make a difference, then I'll be astonished!
Edit - OK amazing, in the time it took me to write the above, it's turned into a slanging match!!! Sad.
