NY Times calls it the "largest demonstration for gay rights here in nearly a decade".

Impatient and discouraged by what they see as a certain detachment by President Obama on their issues, gay rights supporters took to the streets of the capital on Sunday in the largest demonstration for gay rights here in nearly a decade.
Unlike previous marches promoting gay civil rights, the rally was primarily the undertaking of a new generation of gay, lesbian, bisexual and transgender advocates who have grown disillusioned with the movement’s established leadership.
Known as Stonewall 2.0 or the Prop. 8 Generation – a reference to the galvanizing effect the repeal of California’s same-sex marriage law had on many young people – this group of 20-and-30-something activists are at odds with gay advocates who are urging patience as Mr. Obama grapples with more pressing pieces of his domestic agenda like health care reform and the economic recovery.
“I think this march represents the passing of the torch,” said Corey Johnson, 27, a protester and blogger for the gay lifestyle website Towleroad.com. “The points of power are no longer in the halls of Washington or large metropolitan areas. It’s decentralized now. You have young activists and gay people from all walks of life converging on Washington not because a national organization told them to, but because they feel the time is now.” (continues here)
