Hi Debraj ,
Your comment about Hui would apply to most of us !
If a poster frames his / her problem clearly , with adequate data , and adequate explanations , then there would be no clarificatory posts ; however I have seen that a lot of people who post questions lack time or words ; in fact , in one of my earlier posts , I had mentioned that the poster was releasing information in homeopathic doses !
Those of us who don't like to / wish to waste time on such questions , just ignore them. There are a few , like Hui , who feel obliged to answer ; this means that clarificatory posts are required. I think this should be appreciated.

P.S. Just as I finished posting this , I saw a question on Financial Modeling ; can you please answer this question fully , so that only one post is required to resolve this poster's problem ?
