Philadelphia and Los Angeles may be worlds apart in terms of culture, celebrities and fandom, but apparently the two major metros have something in common: their Twitter users drop a lot of F-bombs.


A new project called "Twitter heatmap" shows the rudest and most polite users of social media by scanning 462 locations in the United States for the phrases "Good morning" and "F--k you." The heatmap was created by Ukraine-based firm Vertaline.


The "Good morning" maps are based on tweets from June 20 to July 1, while the "F--k you" maps were done from July 14 through July 24.


While the maps don't show exact locations, they allow us to draw a few conclusions:


– So-Cal and the Philadelphia-metropolitan area has some of the most active Twitter users. Not only did they register the highest concentration of "F--k you," but also the highest concentration of "Good morning."


– People in North Texas apparently use Twitter to say "Good morning" a lot. The area was brighter than Rudolph the Reindeer's nose for the key phrase.

– It appears that people in Fargo, N.D., have never heard of a Twitter or are still figuring out how to work the darn thing.
