HOT or NOT Gossip does exactly that, it covers all of the latest hot and juicy celebrity gossip. Not only that, members can now vote on the "hotness" or "notness" of celebrities.
Another fun new item is the Celebrity Look-A-Likes feature which lets you view celebrities that resemble each other such as the example below of Sarah Palin and Tina Fey.
The nice thing about Look-a-likes is that it isn't relegated to just comparing celebrities. Other things are examined such as this eerily similar Ad campaign.
HOT or NOT Polls is a new feature that will let members rate candidates from popular shows and current events on a 1-10 "hot scale." For example, athletes from the 2008 Olympics would have been featured in this area. Obviously, political figures will see a great deal of action in the coming weeks. The results of the polls will be updated on a daily basis.
The HOTLIST feature seems to be the best and most useful new addition to the service. It lets you share your interests with the HOT or NOT community by rating and sharing what you think is hot in pop culture (Celebrities, Products, Gadgets, Food, etc.). It's a visual collection of all the things you like most, which reveals a lot about people.
You can show off your interests on your profile and even add them to your favorite sites (MySpace, Bebo, Xanga, etc.) via embeddable widgets.
