The practical pragmatic reason is that threads are limited to 300 messages.
Why do we have a 300 limit rule? Presumably its so that debates don't go on for all eternity. But often what happens with popular thread that end up getting closed is that someone simply makes a sequel thread. In which case, the 300 post limit didn't really prevent anything.
While there's nothing inherently wrong with chat-style exchanges, this board is oriented more toward and attempts to encourage thoughtful and carefully considered discussion. We do have a chat room.
Understandable.
However, not every one is on chat when a question needs to be asked. For instance, to my recollection I don't think I've ever seen you on Chat. How then would I be able to contact you for something?
I guess I just don't understand why all posts need to be lengthy discourses, when sometimes being brief and to the point says it all.
"It is not the critic who counts, not the man who points out how the strong man stumbled, or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena; whose face is marred by the dust and sweat and blood; who strives valiantly; who errs and comes short again and again; who knows the great enthusiasms, the great devotions and spends himself in a worthy course; who at the best, knows in the end the triumph of high achievement, and who, at worst, if he fails, at least fails while daring greatly; so that his place shall never be with those cold and timid souls who know neither victory or defeat." -Theodore Roosevelt
