Section Hiker - This is a great mix of beginner to advanced info.  It is a realistic, down-to-earth approach.  The gear reviews are NOT Backpacker Magazine style (i.e., written to sell gear and magazines), which means I trust them.  It is a little heavy on east-coast related hikes, but that is to be expected based on the author's locale.  

Andrew Skurka - Skurka has done more big trips (i.e., 1000's of miles) than just about anyone else.  It is sometimes a little heavy on marathon training and ultra-racing stuff, but solid place to get good information.

Pmags - This is a source of good info and some ideas for places to visit (especially in Colorado).  The use of passive voice bugs me a bit, but who am I to complain (being an engineer)?  

The Hiking Life - He doesn't post as frequently as the others, but what he does have is worth reading.  

Adventure Alan - Good reviews and recommendations.  Some content does seem be reused a bit, but a great wealth of information.

Backpackinglight - This used to be about the only place I visited.  Great reviews, amazing articles, nerdy stuff engineers like (the founder has a PhD in Civil Engineering), but it has seemed to be heavier on the gear swap posts lately that aren't as interesting to me.  That said, there is a wealth of info in the comments/posts from several years ago.  I do a lot of Google searches that start with backpackinglight and then whatever subject I want to learn more about.  A lot of articles now require subscriptions to read.  I stopped subscribing a few years ago, but if you are just getting started (particularly if you are focused on really cutting pack weight) it is worth your time to go back through articles and posts. 

CaptureLandscapes - Lots of good tips and information about shot composition as well as Adobe Lightroom (which I love) and Photoshop. 

LoadedLandscapes - This site is focused on landscape photography with good hints and tips about photography as well as post-processing software.
