This site is hosted on DreamHost.  These guys are great and quick to help when I fuck it up (which I do).

I use WordPress as the engine behind the blog.  It’s free. It works great.  ‘Nuf said.

To edit posts I use MarsEdit.   Cheap (as in not free) but works great.  For more complex things or other web tinkering I use Coda which also works really well.  

For photography and printing I mainly use Adobe’s Lightroom.  Started using it because it functioned well on my old 12″ PowerBook. I gotta say it screams on the newer hardware.  I also use Pixelmator for further graphic tinkering.

I’m also using the SmartArchives and RelativeDates WordPress plugins by Justin Blanton and Twitter Tools from Alex King.
