That's an interesting opinion/answer relache.... Heaven help us if yet another recipe for cooking rice or why dogs need to be neutered is ever published eh! (raised eyebrows!) Amazing! Would YOU mind advising Everyone On the Net exactly How many Opinions are allowed in the World? (Or should I Ask THAT Question instead of This one!) The hub linked here did not answer all the specific issues, including those asked here! And if YOU feel that Wikipedia provides ALL the Inside and Relevant Information.... Then I guess we should be glad that other libraries still exist - Do You Know what I mean? I asked this question simply because it is an Extremely Complex and highly subjective issue - In MY Opinion... and one which has the potential to provide or open up further areas of discussion! Clearly, it is Your Opinion that once a couple of hubbers and Wikipedia have written about something... the subject has been covered! Wow... Thanks for your opinion/answer.... Did you actually consider the Depth of the Question before you tried to smudge it?
