A company called Vertaline scanned millions of tweets a day to try to figure out which cities are most polite  and which are the rudest.

They tracked the use of two phrases on Twitter: "Good morning" and "[blank] off"...to see which cities said each one most often.

The city most likely to wish you good morning on Twitter is...Lubbock, Texas.  Los Angeles says it a lot too.

And even though there's an old cliché about New Yorkers being rude, they tweet "Good morning" more often than people in the South.

The city most likely to tell you to "[blank] off" on Twitter is...Buffalo, New York.

Los Angeles ALSO says that a lot and so does Dallas.

You can take a look at hour-by-hour "heat maps" for the two phrases at Vertalab's website.
