Warren Buffett joins Twitter; says women are key to our prosperity.

Yesterday Warren Buffet joined Twitter and since then his followers have been growing exponentially. I’m excited. You see, after his first tweet, “Warren is in the house,” his second and only other tweet was this:

It’s an excellent essay on women and the economic future of our country. He marvels at how far we’ve come since 1776 using only half of our talent. His message to men:

Fellow males, get onboard. The closer that America comes to fully employing the talents of all its citizens, the greater its output of goods and services will be. We’ve seen what can be accomplished when we use 50% of our human capacity. If you visualize what 100% can do, you’ll join me as an unbridled optimist about America’s future.

I’m a big fan of Katharine Graham, and found her relationship with Buffet to be one of the most interesting parts of her memoir. In this essay, Buffett gives us a glimpse of their relationship from his point of view, and how he sees things being different these days for his daughter.

I told Kay that she had to discard the fun-house mirror that others had set before her and instead view herself in a mirror that reflected reality. “Then,” I said, “you will see a woman who is a match for anyone, male or female.” I’m happy to say that funhouse mirrors are becoming less common among the women I meet. Try putting one in front of my daughter. She’ll just laugh and smash it.

I find it interesting that Buffett created his Twitter account just days before the 2013 Berkshire Hathaway annual shareholders meeting and this is his only tweet. Will he focus more attention on women in business tomorrow? I hope so.
