The discussion on Gentoo's post about things that have changed for photographers brought up a good point: it's easier to learn in the digital age because there are so many places where you can see other photographers' work and maybe even get inspiration for techniques you can try.
What are some of the places you look at photos online?
Here are a couple of my favorites to start the discussion:
The Big Picture—photo essays from The Boston Globe
photo.net—user galleries with some amazing shots (and some not so), also tutorials for different styles of photography
I also occasionally check out BBC's day in pictures, which can be found here.
