The dangers of Twitter have surfaced yet again and this time a high-profile men's basketball coach is bowing out of the social networking Web site's community as a result.

George Mason's Jim Larranaga tweeted what he told the Mike Wise Show was a "tongue-in-cheek," "sarcastic comment" mocking a recent piece of NCAA legislation regarding the admittance for institutions to provide, "fruit, nuts and bagels" to student-athletes after practice or workouts. Larranga's comment, which was directed toward a rule that he admits is "a very good rule," noted that cream cheese is absent from the approved legislation.

Larranaga told the Mike Wise Show, "I made a comment that has been blown out of proportion and used to fuel some other columns, and I didn't feel good about that."

And as a result? "'Well, that kind of ends my twittering," he said.

A classic example of a lesson learned the hard way, administrators of tennis' US Open hope to keep their competitors from experiencing the same backlash from irresponsible tweeting.

Scattered around the grounds of USTA Billie Jean King National Tennis Center are posters with the header: "Important. Player Notice. Twitter Warning."

According Nbcsports.com, the notices address how Twitter may impact the Tennis Anti-Corruption Program Rules, namely "information about the likely participation or likely performance of a player in an event or concerning the weather, court conditions, status, outcome or any other aspect of an event which is known by a Covered Person and is not information in the public domain."

The warning applies to players, coaches, agents, family members and tournament staff.

Do you think Twitter warrants this kind of action at high-profile competitions?

Do you think it's fair to limit and/or monitor what athletes are tweeting while off the field of competition?

Can athletic departments limit the tweets of their student-athletes? Can institutions limit the tweets of their students?
