Best photo sharing sites

Of course you have Flickr and photobucket but I have come across a few better photo sharing sites that are a lot of fun and you can meet some good people. One of the sites is called Viewbug http://www.viewbug.com/, you can post all of your photos for free and it gets better, you can enter monthly photo contests for free and they have weekly winners as well. You can actually win some money just for taking great photos.
Another good site is called Deviant Art http://www.deviantart.com/ where you can post photos for free or pay for a better account. You can sell prints if someone wants to buy them and everyone gets a free print account.
So enjoy the sites and have fun.
