Ragan didn't wind up covering the PRSA conference in Philly, so to figure out what happened at the Karen Hughes luncheon keynote that I predicted might bomb, I've had to troll the Internets.

I haven't found much either way, and I haven't heard any reports of booing.

But what I have found—a blog quoting people's Twitter tweets during Hughes' speech—is even more chilling.

Imagine being a public speaker and wondering how you're going over and knowing audience members are Twittering the world with their impressions—while you're still talking!

Some of these folks appear to be booing Hughes, not audibly in the room, but silently, to the whole world.

Check it out here.
