Yesterday was the big HARO/Twitter all day giveaway hosted by Peter Shankman (@skydiver). It was really interesting because he was broadcasting live from his home office and Twittering a trivia question every eight minutes giving away thousands of dollars in prizes.
I began watching and entering at 6:30am when he went live, until Twitter got so bogged down by 11:00am that I wasn’t able to get site updates for 5 minutes.
I have found other contests on Twitter:
TWinners — Tweeting other Twitter contests
Tweet Contest — Tweeting other Twitter Contests
I Heart Contests — Tweeting contests from all over the world
Win Sweepstakes — Tweeting U.S. sweepstakes
Contest Hunter — Tweeting contests
Twit-2-Win — Tweeting contests
Win Prizes — Tweeting giveaways on their feed
Tweet-a-Prize — Twitter-based scavenger hunt
Some of your favourite websites also have Twitter feeds:

I even found one blog that helps you win on Twitter:
