Printed newspapers typically have geographically limited distribution. So, for instance, if I pick up a copy of the Milpitas Muckraker, I expect it to be centered around the south end of the San Francisco (California, US) Bay Area, and if it refers to Alameda County, well, in general terms that's over on the east side of the Bay, and kinda north.
If, however the Muckraker has a nationally-interesting story in its on-line edition, readers will be coming in from all over, with no clue where Milpitas might be. If the web-page boilerplate merely duplicates what's on the front page of the print edition, they'll continue to have no clue.
A moment ago, I followed a link from Insty (in Tennessee) to a story in the on-line version of the Times Herald-Record... an aggregation, presumably, of at least three former small-town papers. Which has something to do with the Hudson Valley, and towns called New Paltz and Dover Plains.
If I felt like doing some Googling, I suppose I could put this in geographical context. The sidebar ads suggest it's in New York State. But wouldn't it be friendlier to non-local visitors to have some geographical context in the masthead?
