*FILM/OPERA: Continuing with their screenings of exquisitely filmed productions of San Francisco operas, this week the Castro Theatre presents Puccini's Madama Butterfly. You know, the opera where [SPOILER ALERT!] the fragile heroine, geisha Cio-Cio-Sa, kills herself with a dagger at the very end? Over an obsession with some American gent? Yeah, that one.
7:30 p.m. // Castro Theatre (Castro & Market) // $6-$9
SINGLES/WEB 2.0: Lonely geeks descend upon Harlot tonight for "Love 2.0: Socializing The Dating Experience at Web 2.0 Expo." ("This isn't speed dating. This isn’t social networking. This isn’t online dating 1.0." - we're told. You will be meeting "new people in a casual, yet elegant way." What? Anyway, what we do know is that "there will be an open bar for a portion of the event." That there is reason enough to attend.) We're also told that (Flickr and Moo are "meeting for pre-party libations at Kate O'Briens" tonight as well. Check out Valleywag for more Web 2.0-ish frivolity.)
