You need to be careful not to confuse The Answerbank with Chatterbank, Roy. Given that I regard researching useful answers here as my main hobby, I'm probably happiest when then 'serious' sections of AB (such as Technology, Travel and Law) offer me something to get my teeth into; Chatterbank is just a bit of a bonus to me.
However I love it when we occasionally get new members who contribute right across the site. (Sunk is a recent excellent example). I also like to see entertaining posts from the like of Gness (who, alas, isn't here as often as she used to be) and Caran, rather than posts from people who seem only to be looking for an argument!
