This is such a great use of Twitter for promotion at events. HP is running a Twitter-powered scavenger hunt here at BlogHer with product giveaways including webcams and even laptops.
At their booth is a small slip of paper with simple instructions on how to sign up for Twitter (and several live laptops people can use to do so) and how to follow their special account @HP_BlogHer2008 for the clues and challenges.
Very cool.

Laura,
I am reading your posts from blogher with great enjoyment and envy! Wish I was there and hey, I thought the conference was in New York, am I ever confused. SF is just down the coast!
namaste,

I’m quite intrigued. How did the scavenger hunt work using Twitter? Is there a link to the rules or the process that HP used for the game? I can imagine several ways to do this.
