Maggie Gyllenhaal Thinks Taylor Swift Is 'Great', Jack Dorsey's .

The holiday season has its part of lavish parties - some exist for the highly legitimate use of providing an apology to set up, others for an actual cause. Last night`s WITNESS`, co-founded by Peter Gabriel, Focus for Change Benefit Dinner & Concert at Roseland was unquestionably the latter.

Peter Gabriel did not grace the point as aperformer, although he said he was looking ahead to a pair between Corvus and reggae legend Jimmy Cliff.

WITNESS provides education and subscribe to individuals and groups to use video to document human rights abuses. It`s not much that Tiananmen Square and Neda Agha-Soltan are discussed on the red -or more fitly in this case, black - carpet. But last night they were brought up by guest and presenter Maggie Gyllenhaal - accompanied by similarly be-voweled husband Peter Saarsgard - as examples of the king of images to force change.

"I think video impacts you in a different way," she said. "I mean nearly the Tiananmen Square massacre and being 8 or 9 days old and beholding that man standing in front of those tanks and being willing to gamble his lifetime for what he believed in and that did shift my life. Or Neda, the woman from Persia who we saw killed last year." When asked about her brother Jake`s love life, she was less effusive. "He`s an adventurer," Saarsgard offered.

And how did Thanksgiving at their well-appointed Park Slope brownstone go? Especially given that 29-year old Jake Gyllenhaal reportedly attended with his new girlfriend, 20-year old Taylor Swift, she of the doe eyes and angsty lyrics about being unworthy and awkward?

"It was great," was all Gyllenhaal offered, as both she and Saarsgard visibly closed down and promptly moved on.

We also caught up with Jack Dorsey, the unfairly attractive co-founder of Twitter, who waxed lyrical on freedom of speech.

"The most interesting thing about any technology that`s blocked is that people get a way to run around it. It`s not up to companies, it`s not up to organizations, it`s not up to government. It`s up to individuals. They ever see a way round it."

We felt so empowered, all of a sudden. But we had to know - does he ever not interact with technology? Might he, say, read a word? The response is yes, but on the iPad. No musty books for the co-founder of Twitter! Turns out he`s reading Alain de Botton`s The Pleasures and Sorrows of Work.
