Left-leaning bloggers have had a tremendous impact on the Democratic Party.

Facebook's headquarters is a two-story building at the end of a quiet, tree-lined street. Zuckerberg nicknamed it the Bunker. Facebook has grown so fast that this is the company's fifth home in six years - the third in Palo Alto. There is virtually no indication outside of the Bunker's tenant.

Experience - the wisdom that enables us to recognise in an undesirable old acquaintance the folly that we have already embraced.

To put it bluntly, I feel relevant and valuable, and I am struggling to understand why, when women reach age 65, they encounter an invisible barrier of perception that says it's time to walk away. Shouldn't we have a choice in the matter? Shouldn't our experience and energy be worth more?

There used to be a huge hole in my life that I wrote many albums about. I didn't realise it was a wife-and-daughter-shaped hole. They've plugged that gap. Everything I do, I do for them now. When daddy goes to work, it's daddy going to work, not Rob going to work. I feel like there's a purpose to everything.
