We've been remiss in informing you of this: Cal Henderson, the eminently scalable Flickr engineer, and Leah Culver, the shrill-voiced cofounder of Pownce, San Francisco's favorite way to share MP3 files while evading copyright cops, broke up some time ago. (We hear it wasn't exactly his idea.) But don't feel sorry for Henderson, or Culver. She has no shortage of suitors — including, it seems, Technology Review editor-in-chief Jason Pontin, who was taken enough with Culver to put her on his magazine's latest cover. Pontin's married, but a man can dream, can't he? Sorry, Jason: We now hear Culver's hooked up with a Googler. (Photo of Henderson by magerleagues)
