slagosphere
n.— «In a recent interview about his controversy-baiting wife Ayelet Waldman, novelist Michael Chabon condemned “the slagosphere”—that merciless virtual coliseum in which anyone with a DSL can publicly eviscerate any celebrity, political figure or, heck, private citizen who happens to offend.» —“Escape from Fantasy Island” by Diablo Cody City Pages (Minneapolis, Minnesota) Apr. 12, 2006.
