Steve Ballmer

If you look at companies with upside potential, Twitter's right there. They've established a brand in a world where it's extremely difficult to establish a brand. It's a global brand, people recognize it, people want to let you know what their Twitter handles are, etc.

I'm very, very bullish about our prospects, and as I tell our board, as I tell our employees, this is the time to invest. There's so much opportunity. Let's just invest in that opportunity, and really get after it.

Personally, I like to juice up several different kinds of fruit and vegetables - which may include various combinations of bananas, red bell peppers, apples, carrots, celery, broccoli, spinach, parsley, tomatoes, cucumbers, etc.
