For those of you who host giveaways on your blog or website and don't get a lot of entries, I wanted to mention Giveaway Scout. You submit your giveaway to them and they send the information out through various places such as twitter and facebook. They will also scan your blog automatically looking for any new giveaways that you may have. It's a great way to get more entries and more traffic to your blogs!
They also have this great widget that you can put on your blog showcasing some of the giveaways that are out there!
