Manny Pacquiao joins the Twitterverse!

Pacman knows, Pacman tweets. Pound-for-pound king Manny Pacquiao has officially joined social networking site Twitter.

With twitter name @mannypacquiao, the eight-division world champion tweeted, “Kamusta kayo hi everybody” in his verified twitter account last February 20.

The Filipino ring icon has not tweeted since, and has only followed 12 people—one of which is television host and comedian Jimmy Kimmel, who had Pacquiao as guest on his show.

It took two days before Pacquiao's fans fully picked up on the news about his Twitter account, but by Tuesday afternoon he has eclipsed the 4,000th mark of followers—a testament to his worldwide popularity.

Though there has not been any confirmation yet from Pacman himself, his account has a verification seal from Twitter.

Pacquiao joins other boxing greats who is hooked with the networking site—including compatriot Nonito Donaire Jr., Floyd Mayweather Jr. and even Sugar Shane Mosley, who has a very active Twitter timeline.

Mosley, who is set to fight Pacquiao on May 7 at the MGM Grand is Las Vegas, has shown general congeniailty towards Pacquiao—even tweeting photos of their stare down on his account for amusement.

Mayweather, who remains reluctant in fighting Pacquiao, meanwhile, seemed more hostile as he tweeted video links of Pacquiao's three defeats—against Erik Morales, Medgoen Singsurat in 1999 and even as far back as Pacquiao's first loss to Rustico Torrecampo in 1996—last week.
