Any good photography websites?

I'm trying to get into photography.
I just bought a Nikon D3100
I currently browse PictureCorrect.com but I was wondering if there are any other good websites for picking up tips and whatnot?

National Geographic often has great photos.

Flickr.com

Join it, upload photos, add tags to the photos, join groups, add your photos to groups, look at group discussions, post a new topic, look at Explore for inspiration.

Http://strobist.blogspot.com/ and http://markhancock.blogspot.com/ are 2 good websites.
