The requirement to post your location is an aid to those shopping in the BS&T forums, so they don't need to open a thread to know what state the advert is from. TFL went a long time without the location-in-title requirement. It is a fairly new requirement. If all members put their state of residence in their basic info that is displayed below their username and kept it current, we wouldn't be having this discussion.
"The irony of the Information Age is that it has given new respectability to uninformed opinion." - John Lawton, speaking to the American Association of Broadcast Journalists in 1995
