People are complaining about the boards not being split between Portland, Seattle, etc. Understandable, especially when both Portland and Seattle have Pioneer Squares.
However, if people just indicate in their subjects where it refers to, this wouldn't be too much of a problem,eg:

Personally, I think the chowhound folks should suggest something like this as a standard.
