@shri - one thing I noticed that drags the thread down is the multi quote thing.
HC, DH and as few others are big users of it and all it does is allow to cherry pick sentences/paragraphs and move them out of the context of a general post...and of course you can write a good /clear post but have a few "so so" sentence....and guess what...that's what will be used to kick start a petty argument.
You would think grown up men would see that and stop right there but clearly that's not the case. Maybe to help, would it make sense to just stop that feature?
