The New York Times was paying attention to Pres. Barack Obama’s Twitter account over the weekend, it seems, and noticed that the president himself posted an update.

According to the Times, from now on, any tweet sent from his account that has “-BO” appended is from the man himself, while the rest come from staffers. Most of the tweets during his 2008 campaign came from staff members, the blog notes.
