How I see it is....
There are different people on here....some like to come on often to 'chat' with others, and get to know each other more. Others purely want to use the site as what it was originally intended - a question and answer site. Personally I like looking through questions in different topics, answering where I can. However, occasionally I see a more fun chattier post that I would also like to join in on.
Because people can choose to ignore the threads they are not interested in, the main problem I see is that in Body and Soul, proper questions get pushed down the page far too fast, and there is less chance of getting a decent number of replies. The Chatterbank section went out of control, but it obviously kept the chatty posts out of body and soul. I'd like to see a similar section to Chatterbank (re)introduced, so those who want to chat can, and those who want to post "proper" questions can do so in B&S without it disappearing so quickly.
