Ella I think it's ok to start a thread with a real question for advice or help, even though they might die a death quickly, or as soon as the question has been answered. (I did this recently asking for advice on nail products, got the answer, end of thread as far as I'm concerned) but I would agree that there are sometimes too many "opinion" type threads on what might be deemed light topics.
That's not to say there is anything wrong with a bit of froth on here, but a good variety of topics and issues will usually mean that most members will find something of interest.
(Hope this has come across the way I meant it!)
