Kyle Slattery, friend and coworker who is studying in Germany this semester, recently wrote "How to take better photos" which is a small compilation of tips that he's gathered over his few years of taking photographs.
Blog posts like this are everywhere. Page through my Photography tag and you'll see a ton of tips and tricks that I've linked to in the past. What separates Kyle's post from others is that he points out exactly what has helped him, rather than just a laundry list of tips that may help people shoot better.
Oh, and I love what he's been doing with his photos section. He uploads his photos to Flickr and they are automatically synced with his site in an orderly fashion. Definitely a different approach but one that I think works extremely well.
