Do you feel like Facebook is becoming too invasive? Some users are complaining that the social networking site’s latest expansion shares too much personal information. Our own Jim Colgan will explain how the “like” system works and why so many are up in arms about it.

And as Anna mentioned earlier, we’ll be closely reporting on the nomination of Elena Kagan and how her appointment would affect the diversity of the nation’s highest court. We’ll also examine her own record when it comes to diversity. The Root reported today that, “of the 29 law professors hired by Professor Kagan, only one was a professor of color. None were African-American or Latino. Only seven were women.”  Earlier today we started a conversation here on our website asking listeners what they think is most important attribute in a Supreme Court nominee. Give us your take by commenting below or calling us at 1-877-8-MYTAKE.

And across the pond, British Prime Minister Gordon Brown announced he would resign within months as the leader of the Labour Party. Last week’s general elections there resulted in a hung parliament where no single party won a majority. Brown says he accepts the results as a “judgment” on himself and is stepping aside. We’ll bring you the latest on that story tomorrow morning.

Anna Sale here on the day shift.

We started the week getting to know Elena Kagan — Obama's pick to replace Justice John Paul Stevens on the U.S. Supreme Court. Tomorrow, we'll look beyond her biography and resume to the politics of her Senate confirmation. We will also look at how her addition would change the demographic mix on the court. If she is confirmed, she would be the third woman and the youngest justice on the current court. There would be no Protestants on the court and every member will have graduated from Harvard or Yale. But how much do you think this matters? We're starting that conversation early online today: What do you think is the most relevant attribute in a nominee?

We are also continuing to watch developments in the Gulf of Mexico and how the thinking is changing about the best way to stop the flow of oil there. After ice crystals foiled the plan to cap the well with a massive dome, engineers are now considering using golf balls and shredded tires to plug the leak. We're reaching out to engineers today to see how they are developing these Plan B's, C's, and D's. 

Afghan President Hamid Karzai arrives in Washington today for his first visit since his reelection. It's also his first visit since the Associated Press reported last month that Karzai threatened to join the Taliban (Karzai denied those reports). We're watching the tone of Karzai's reception and the expectations for his meetings with Obama and cabinet officials this week.

Finally, 40 years after The Beatles' released their last album, "Let It Be," another American music legend is trying her hand at the the band's tunes. Roberta Flack will release an all-Beatles cover album later this year, tentatively titled "Let It Be Roberta." Her connection to the band goes back decades. She remembers her career taking off just as "Let It Be" was released. She also lived down the hall from John Lennon in the Dakota, the New York City building where Lennon was shot in 1980.
