The (relatively) old joke among lawyers is that the "e" in email stands for "evidence," since emails had the unfriendly tendency to reappear in court; so you might say that the "t" in Twitter stands for "transparent," in that both you and the police can see right through the online microblogging service.

American law enforcement requests for Twitter user data increased 20% in the second half of 2012 compared to the first half of the year, according to the service's biannual transparency report, which was released Monday as the part of the company's ongoing openness efforts.
