Twitter says it has more than 100 million active users. With that many folks on the six-year-old microblogging site, Twitter is always good for a few surprises.
There are those who surprise by what they say but there are a few Twitterers who surprise you by being on the site in the first place. Here is a list of those people:
Stan Lee: @therealstanlee -- At 89 years old the Marvel Comic legend still has plenty to say.
Queen Rania Al Abdullah of Jordan @QueenRania V -- It's not every day you get insight into the happenings of a real life queen.
Rupert Murdoch: @rupertmurdoch -- Even at 80 years old and in the midst of a phonehacking scandal, Murdoch jumped into the Twitter pool last month.
Don Rickles: @donrickles -- The 85-year-old king of insult comedy shows he's as sharp as ever on the social-networking site.
The pope: Pope Benedict XIV started the @Pontifex Twitter account, which has since been taken over by Pope Francis.
Mark Zuckerberg: @finkd -- It's always surprising to see the creator of the world's biggest social networking tool on another site. All though Zuckerberg hasn't updated
Dalai Lama: @DalaiLama -- The Buddhist leader's inspirational musings work well with Twitter's format. How much input the Dalai Lama has with his account is another question.
Amy Winehouse: @amywinehouse -- When someone's dead, it definitely qualifies as a surprise when you see them active on Twitter. Her account is still used by the Amy Winehouse Foundation to update fans and supporters.
Hugh Hefner: @hughhefner -- The 85-year-old Playboy founder fired off his first tweet back in 2008, ahead of the cultural curve.
Cher: @cher -- The 65-year-old diva has been mostly out of the public eye as of late, but on Twitter, she has more than 478,000 followers watching her every move.
