 Pigs aren’t flying, lambs aren’t lying down with lions, and hell isn’t getting any cooler. But Warren Buffett is joining Twitter. 
  
 (It’s official. Buffett published his first tweet at 12:20 p.m. Eastern Time.) 
  
 Warren is in the house. — Warren Buffett (@WarrenBuffett) May 2, 2013 
  
 Buffett, the chairman and chief executive of Berkshire Hathaway Inc. who once admitted he didn’t know how to check his voicemail, is being dragged into the social-media age by his friends at Fortune. He’s sitting down for an interview with the magazine at noon for a panel called “Warren Buffett on Women and Work…and other Wisdom.” 
  
 The magazine is billing it as his first-ever interview to incorporate social media. And in preparation for the big day, Buffett’s assistant revealed the billionaire investor is setting up a Twitter account and will author his first tweet at some point today. 
  
 And she confirmed that existing Twitter accounts purporting to be Buffett, including one that’s been telling over 127,000 followers to “stay tuned” for news since 2009, are all bogus. 
  
 With powerful friends like Microsoft Corp. co-founder Bill Gates able to retweet pronouncements from the Oracle of Omaha, expect Buffett’s follower count to climb quickly in the days ahead. 
  
 Buffett’s foray into the Twittersphere is notable in part because of his professed aversion to technology. He once said he missed a message about a potential deal to bail out Lehman Bros. before it collapsed because he didn’t know how to check the voicemail on his cell phone. For years, he repeatedly declined Gates’ attempts to send someone over to set up a computer in his home. And he still doesn’t have a computer on his desk at his office. 
  
 But signing up for a Twitter account is no guarantee that Buffett will become a regular and sustained user of the micro-blogging service. Carl Icahn launched a blog to chronicle his thoughts on corporate governance, and even hired a reporter from Reuters to contribute, but the project lasted for less than a year. The site, called The Icahn Report, hasn’t been updated since 2009. 
  
 But Buffett’s folksy aphorisms seem like they could be a good fit for Twitter. As Buffett once (almost) said: “B fearful when others r greedy. B greedy when others r fearful. #WordsToLiveBy” ||||| Hopefully this means we'll hear from the Oracle of Omaha on a more regular and informal basis. 
  
 Buffett has established himself as the most successful investor in history. 
  
 And he has never kept his investing methods secret. 
  
 In fact, when he shares his tips, he often does so in an approachable and entertaining manner. 
  
 So, as we get ready for this week's annual meeting of Berkshire Hathaway shareholders, we reflect on some of Buffett's best investing quips. 
  
 We compiled a few of Buffett's best quotes from his TV appearances, newspaper op-eds, magazine interviews, and of course his annual letters, which are always-must reads. 
  
 Investing novices and experts alike can learn from the advice that the he has articulated through the years. 
  
 If we've missed any of your favorites, let us know in the comments. ||||| Updated to include Warren Buffett's first and hopefully not last, Tweet. 
  
 NEW YORK (TheStreet) - Warren Buffett, the 82-year old head of investing conglomerate Berkshire Hathaway (BRK.A) has joined Twitter, countering some notions that the 'Oracle of Omaha' and International Business Machines (IBM) investor has little tech savvy. 
  
 At a Thursday afternoon Fortune Magazine panel titled "Warren Buffett on Women and Work...and other Wisdom," Buffett made his first ever Tweet. 
  
 "Warren is in the house," Buffett wrote, using handle @WarrenBuffett. 
  
 "It means my family can no longer say I am lodged in the 19th century," Buffett said of his first Tweet, on a Fortune Magazine streaming panel discussion with Pattie Sellers. 
  
 "It's pretty daring but I'll try," Buffett said as he was about to Tweet. "Does it bite?" 
  
 "We have set up an account," Debbie Bosanek, Buffett's assistant said in a brief phone interview withearlier on Thursday. 
  
 Bosanek had said Buffett's first tweet would center on thepanel on women and an article Buffett wrote, which is featured on Fortune.com 
  
 "I believe the first one will be about this article," Bosanek said. She also cautionedthat all other accounts claiming to be Warren Buffett are fake. 
  
 "Any accounts out there that purport to be Warren Buffett are bogus," Bosanek said. 
  
 Joining Twitter may help Buffett counter reports he is decidedly tech unsavvy. Some media reports say Buffett doesn't have a computer in his Berkshire Hathaway office, whole others have noted the 'Oracle of Omaha's' problems with cell phones and voicemail. 
  
 Berkshire Hathaway has also avoided investing in tech sector giants likeand. Buffett has claimed he isn't able to fully evaluate such stocks. 
  
 Buffett's introduction to Twitter comes just ahead of Berkshire Hathaway's annual shareholder meeting in Omaha, Nebraska on May 4. 
  
 "It is really going to be a good one this year," Bosanek said of the meeting, while advising investors to bring a coat as a result of unseasonably cold weather. "Everything else will be perfect." 
  
 Buffett's handle @WarrenBuffett gained nearly 10,000 followers within minutes of the 'Oracle's' first Tweet. His account was verified on the social network within about 15 minutes and now carries a blue checkmark. 
  
 Buffett's account states he is Chairman and CEO of Berkshire Hathaway and provides a link to the company's website 
  
 Already, Buffett and his assistant Bosanek have a notable presence on the social network, which allows authors to make posts in 140-character increments and post links, photos and videos. 
  
 President Barack Obama used an op/ed written by Buffett in thecomparing his about 17% income tax rate as a billionaire to Bosanek's tax rate of over 30% to describe why millionaires and billionaires aren't paying their fair share of taxes. 
  
 Obama subsequently coined a piece of legislation called the Buffett Rule, which has taken off on Twitter under hashtag #BuffettRule. 
  
 On April 9, President Obama referenced Buffett in a tweet advocating a higher tax rate for top income earners. Obama used the #BuffettRule hashtag. 
  
 "RT if you agree: Congress should pass the #BuffettRule next week so middle-class families don't pay a higher tax rate than millionaires," Obama wrote, in a tweet that was favorited 208 times and retweeted 5,218 times. 
  
 To be seen is whether President Obama and Buffett will follow each other on Twitter or whether retweets will come with more frequency. 
  
 Others have used Twitter to promote Buffett and Berkshire's upcoming shareholder meeting. 
  
 "Berkshire annual meeting or Kentucky Derby Day... For me, Berkshire by 10 lengths," Mario Gabelli, head of GAMCO Investors, wrote on |||||
