I just found a GREAT new place to list your giveaways if you're a blogger. It's called Giveaway Scout.
Here is what they say:
Giveaway Scout is a giveaway search engine. Our users subscribe to receive updates on the latest giveaways on the web. Add your blog and your giveaways will be exposed to our large network or users.
You have two ways to include your giveaway on their site:
1.Submit your blog. Upon approval they will scan your blog regularly for giveaways and list them (free)
2.Promote your blog in a sponsored position to get higher traffic to your giveaways fast. Sponsored listings get up to 10 times the traffic of regular listings.
I have been trying to get more traffic to my giveaways and think this is a great way to do so.
