Warren Buffett has sent his first tweet on his brand-new account, @WarrenBuffett. It reads, "Warren is in the house."
Buffett sent the tweet during a live streaming video interview with Fortune to promote his editorial in the magazine on why he's "bullish" on women.
Host Pattie Sellers asked if he was ready to try Twitter. He replied, "Pretty daring, but I'll try," and then asked, "Does it bite?"
After sending the tweet, he asked, "Who says you can't teach an old dog a new trick."
Just minutes after the first tweet, Buffett's account had almost 10,000 followers and that number was growing rapidly.
