There are lots of great sites (like this one) for photography tips and tricks, but have you considered checking out your camera’s manufacturer’s site?
Canon has updated its Digital Learning Center, which includes interviews with pros, tips on using their cameras and printers and photo contests. And Nikon recently created the Nikon Digital Learning Flickr group in conjunction with the Nikon Digital Learning Center and the Nikon School. Nikon’s offering feedback for your photographs and tips from the pros as well as assignments you can try to improve your shooting.
