If you like nature photographs (or any kind of photos for that matter), you will love these 2 websites. I stumbled upon them and I think they are absolutely gorgeous. If you're a friend on Facebook, you'll know this already of course!!
I'm particularly fond of this photo of antelope canyon (I have no idea where that is but I want to go there!)
Hongkiat.com: plenty more on that website - advice to bloggers, designers - there are even facebook tricks and tips, and plenty of other technical information. I'm going to have a good look through - there is so much to read!
