Add another speaker to the stellar list for the 10th D: All Things Digital conference, which is taking place in a little more than a month: Aaron Sorkin.

For those who have followed the long and award-filled career of the well-known playwright and Hollywood writer, it’s an astonishing litany of success — from “A Few Good Men” to “The West Wing” to “Moneyball” — filled with more unusually clever lines than anyone has ever penned.

But, most famously for tech, Sorkin also wrote the screenplay (and also won an Academy Award) for “The Social Network,” about the rise of Facebook and its unusual co-founder and CEO Mark Zuckerberg.

The film caused a lot of controversy in Silicon Valley over its depiction of Zuckerberg as an evil genius of sorts, of course, but few can argue that it was not a corker of a movie.

We are excited to talk to Sorkin about that experience, as well as his take on the state of entertainment in the digital age. He’s about to debut a new HBO show in June called “The Newsroom,” set behind the scenes at a cable news show. It deals with the massive changes roiling through the media industry and it begins, natch, with a viral video.

Sorkin is also set to make his Broadway debut as a librettist for the upcoming musical “Houdini.” And he’s also working on another new movie, based on a book about the downfall of Sen. John Edwards, which he’ll adapt, produce and direct.

Sorkin will be joined at D10 — which will be held in Rancho Palos Verdes, Calif., just south of Los Angeles, at the end of May — by a litany of major players in tech and media, including: Apple CEO Tim Cook, New York City Mayor Mike Bloomberg, Oracle CEO Larry Ellison, Federal Trade Commission Chairman Jon Leibowitz and many more.

And we still have more speakers to come, but until then, here’s the famous line from “The Social Network” — something about a billion dollars:

Today, the news was the worst possible for Academy Award-winning actress Jennifer Hudson, an impossibly talented and obviously lovely singer and actress, after the body of her seven-year-old nephew was found after an intense search of the Chicago area.

Julian King was murdered, along with Hudson’s mother and brother, in a horrific crime police are trying to solve now. The main suspect in the case is the estranged husband of Jennifer Hudson’s sister and the mother of Julian.

Hudson used her MySpace page to encourage fans to help in the now tragically-ended search for the boy, and news stories broke all day long, fast and furious. Hudson’s mother and brother were found dead several days ago in the family’s home on the city’s South Side.

No surprise, Internet video is popping up all over, many in the form of condolences to Hudson and her sister in the form of songs and music mashups.

The first and second videos are typical, while the third is Hudson herself singing her signature song–”And I Am Telling You”–from the movie, “Dreamgirls.”

Words cannot express the pain of her family’s loss. But her singing, as you will see, expresses so very much.
