Just because it is a chit-chat forum doesn't mean it shouldn't have structure. Fair enough it is chit-chat meaning you can talk about whatever but each individual thread should still be focused otherwise it would be a big mess.

If you started a thread about Linux and I replied with a post asking about what you ate for dinner last night, the fact of the matter is you wouldn't be pleased.

Anyway I believe QooQ was just using it as an example.
