I just realized that some posts on JasonBlogs.com had been set to private accidentally. This meant that I could see them but no one else could, and I didn’t know they couldn’t. I must have accidentally set a few posts to private when I was going through all my posts, reorganizing and tagging them. And how did I finally figure this out? Ayesha posted in the comments that she could not access my list of SingingFish Alternatives. For the first few days I thought she must be mistaken, but then I decided to use my Windows XP virtual machine to test the page in IE. What I discovered was that when not logged in I could not see the post. And after a few seconds of thought I realized the problem. Yet another reason virtual machines are great for development.
