One of my favorite treats on the net is Joe McNally's blog.  I've been privileged to meet Joe and attend two of his seminars, one in Oslo sponsored by Nikon and the other at his old studio building in Dobbs Ferry, NY.  In addition to being a hugely talented photographer and mentor, he could have a second calling as a comedic writer.  Visit his blog at http://www.joemcnally.com/blog/
