US Vice President Joe Biden just joined Twitter. His account is @VP and he started tweeting on July 4th.

It doesn't look like he's tweeting personally. The tweet is written in the third person and the account's name is "Office of VP Biden." Given Biden's reputation for, er, verbal audacity, if he let loose he'd been an amazing twitterer.

The account @BarackObama used to be written by staffers but President Obama has started tweeting personally in anticipation for the presidential campaign.

Here's the VP's first tweet:
