I have had a bad experience on Yahoo answers, which I suggest you bear in mind. I have a great deal of wisdom, I have had jobs, both in UK and abroad, where I have had to research information in the fields of medicine, law, social sciences, history, literature and languages. I have brought up my childen to adulthood. I used to put up a large number of answers on Yahoo, based on that wisdom and experience, and gained rather a lot of "points". Until some questioner took umbrage at a well-deserved answer, "reported" me, and got me "judged" by what I could only assume to be some nekulturniy teenage male probably younger, less experienced and less intelligent than my own sons. This " judge" did not choose to ask me what I meant, but took the complainer at his word and "punished " me. I was deeply insulted by such offensive and arbitrary treatment, and have removed my wisdom from Yahoo ever since. And, believe me, there are plenty of people on Yahoo answers who could do with it.
