A tipster reported from the scene — a madhouse — at Google's I/O conference for developers, held in San Francisco today and tomorrow:

The Google I/O conference is off to a roaring disaster. The backlog at the prereg[istration] desk was so long (500?) that they told people to just come inside. Conversely the onsite reg was empty.

Did anyone take advantage of the registration gaffe to sneak inside? Your reports are welcome.
