The "What Are You Smoking" thread, or WAYS for short, is an interesting beast. In it's form here, it is pretty much a checklist of what you have smoked during the day. Other that what people are able to extract from it for their own personal use related to getting ideas, it doesn't serve much of a purpose. That being said, it's a part of our hobby and a part of this forum. It is of value to people, so that alone makes it worth while.
It's certainly not common, but on the private forum that I am a member at, the WAYS thread is used as more of a daily diary. Guys will post about what is on their agenda, what they did during the course of their day, who pissed them off or how bad work sucks. It might not be very feasible with a community this size, but in a smaller setting where members are close, it's a nice feature and gives a little insight into a guys life other than what tobacco and pipe he is smoking.
