Hey, Chucho and all,
You are absolutely right... it is inconsiderate, BUT, alot of us click, and its hard not to chat wherever we are, LOL! Sometimes, the question generates discussion that meanders away from the original post. I am not sure I think that is wrong. Sometimes, there is a creativity to it. A question about Dreamtime illicits quotes from songs about dreams. Perhaps, it really has to do with the asker of the question and how they view answering. For me, when I ask a question, I like to hear people's answers, but, I consider it a sort of "salon".... a place to go and discuss what ever comes up because of the question. The only time I get really annoyed, is when people are being mean, or, if the question is really serious and they are cutting up.
So there's my two cents worth, LOL!
