I will eventually start using this forum for my personal blog.
In the meantime, feel free to have a look at two blogs I've maintained in a professional capacity over the years.
As the Project Manager for the Coast Guard Logistics Information Management System, I maintain a blog at http://www.intelink.gov/blogs/_cg-lims for those of you with access to Intelink-U. I export the non-sensitive parts monthly and post it to http://cglims.wordpress.com where anyone can see it.
Way back in the day, before they really called anything a blog, I maintained a blog as the Project Manager for the Aviation Logistics Management Information System. We retired that blog after it served its purpose, but I've kept a copy live at http://teamtaylor.org/almis/ALMISgram.asp. Sometimes it's handy for me to look back and see what I was thinking about software project management while I led in the trenches a dozen years ago.
So grab a cup and have a look!
