I have a small photography blog at http://transienteye.com - mostly daily street photographs and odd longer pieces.
At the moment, it is mainly some experiments in street photography, where I have been trying to figure out a technique and style that works. I tend to alternate between the 5DIII and a compact camera, depending on whether or not I am frustrated more by image quality or the ability to get close with a giant camera...
If anyone is curious, I posted a recent blog entry looking rather subjectively at the difference between the 5D, an Olympus E-M5 (our travel camera) and the Rocoh GR.
I find that trying to keep a blog is useful in that trying to produce regular (daily) images is really helps improve my photography (and for me at least, trying to make one half-decent image a day is much harder than it might sound...).
