Oh, Actually those are articles written by other persons, and are posted here for informational purpose only - of course open for discussion, if anyone wants to. Most of the times, If I dont have anything to comment, then I just leave that thread without replying. I just guess, same applies for others too.
Further, most of the posts here are open-ended discussions with an exception of a few, which can be opened anytime. So feel free to raise your concerns in those thread, and I am sure, readers are going to reply back with equal zeal.
Thanks.
