ADDED IN EDIT : I wrote what follows when the parent comment had been down-voted to 0. As I write this it's been re-up-voted to 1. Who knows where it will go next - I watch with curiousity, but little understanding. ================ Bizarre - some people up-vote people who cross-reference items about the same topic, and others down-vote. I guess it's my background in wiki technology, always wanting to cross-reference and make things tidy, as opposed to the forum mind-set that seems happy to tolerate sprawling, ephemeral discussions rather than create something of lasting value. For one, I hate wasting effort, and wasting other people's efforts. I thought that cross-referencing tuff would help prevent duplication of effort, and generally enrich the information, but clearly there are others who not only disagree, but actively think it's of negative value. <shrug> I don't understand that, but would be happy to read an explanation.
