Hi asilentone,
By doing a Bttt..., (Bring to the top), Iam doing a great service to newbies who missed some threads even oldies who might have been away for vacation. In BTN, old threads are still relevant to bring up discussions as long as the topics are important. As an example, look at BonaFide thread. It is of course an old one but still its a work in progress whose goal is yet to be realised. Look at the Watchtower publications, they are bringing up old topics always just to remind the dubs. Also, these days, there are so many threads, new ones every minutes. So posters have wide latitude to pick up which one to comment on. Its simply a matter of personal choice.
