On of the more anticipated (and most disappointing) panel discussions at SXSW's Interactive conference this week was the appearance by Facebook head Mark Zuckerberg. But, don't blame the young entrepreneur. He was more open and detailed than many had expected during an overcrowded session that had people sitting everywhere in the aisles and on any open floor space.

As Variety details, the crowd unfortunately turned against moderator Sarah Lacy, who was perhaps nervous or maybe over-prepared. I felt bad for her, but by the time that a she ceded control of the panel to the crowd, it was too late to recover at all.
