Twitter trends: Apple event, iCloud, Big East

Apple is due to give a presentation on the morning of September 12 local time, and Twitter users are abuzz with possible announcements that might be made at the event. "iTunes" and "San Francisco" are both trending in the lead-up to the talk as microbloggers discuss the expected unveiling of iTunes 11 and the iPhone 5.

Other microbloggers (and many of the same ones) are meanwhile complaining about a problem with Apple's iCloud that has reportedly left a small number of users unable to access email for 36 hours. Among recent tweets to bring up the subject is one from American actress Mandy Moore, who says, "Dear Apple: Psyched about today's Keynote but would really appreciate iCloud service being restored."

Notre Dame University has announced plans to move to the Atlantic Coast Conference in all sports but football after having been a member of the Big East Conference since 1995. Sports fans are reacting to the news on Twitter, calling it a blow for Big East.
