Public Spheres

So, for English class we had an assignment where we had to think of all the kinds of places for public spheres. Here is my list.

the local news
bulletin boards
billboards
newspaper
grafitti
sidewalk chalk
decals on cars
windsheild paint on cars
tv
movies
facebook
myspace
other websites
classrooms
work offices
phone chain
email chain
fliers
commercials
infomercials
blimps
major news channels
music
concerts
churches

:) that's pretty much all i could think of.
