Talk about the "train wreck" effect. You can't take your eyes off the stories bubbling out of the blogosphere about the fallout from the chaotic interview of Facebook founder Mark Zuckerberg by journalist Sarah Lacy at the South by Southwest Interactive Confab (SXSW Interactive) in Austin.

Wired's got the juicy details as do plenty of bloggers who were there, as well as plenty of twitter posts on the tweetscan.

Audience members, apparently tired of constant interruptions by Lacy and references to her own projects in the interview, essentially said they weren't going to sit for such lame questions and demanded to ask their own.

Here's one passage from the Wired article:

Lacy tried to get the notoriously tight-lipped Zuckerberg to open up. But the discussion rarely strayed beyond the usual business fare and eventually descended into a string of awkward moments punctuated by the audience's heckling.

"Talk about something interesting," one attendee yelled about halfway through the keynote. The remark was met with waves of cheering and applause.

Meanwhile, members of the audience participated in a back-channel discussion on Twitter, with users of the microblogging site directing most of their animosity at Lacy's unorthodox interview technique.

"Never, ever have I seen such a train wreck of an interview," said Jason Pontin on Twitter. "Poor girl, flirtatiously awful tho' she was."

A quick search for "Zuckerberg" on Twitter search service Tweetscan reveals hundreds of posts written by those who witnessed the disastrous interview.

Lacy didn't help matters with her twitter response: "seriously screw you guys."

Memo to journos who get themselves enmeshed in a story and then turn an audience into an angy mob: If you're in a hole and want to get out, stop digging! In this case, Lacy got the audience even more annoyed with her attitude when a little humility would have helped smooth things over. And we wonder why so many people think journos don't have a clue.
