I’m amazed that after all these years, no one has come out with a killer offline blog editor for the Mac yet. It seems like there’s more development energy going towards iPhone blog editors than desktop versions.
I really liked working in Windows Live Writer back when I was a fulltime Windows user. I loved that once configured, the editing window used your blog’s own style sheet so your typing appeared exactly how it would look on the blog. The problem was that the code was pure Microsoft: crap. Full of unnecessary tags and other junk that caused all sorts of problems. And I now only run Windows XP in VMWare Fusion when I absolutely have to.
As I see it, if you want to use an offline editor on a Mac you only have 3 choices, each with its own strengths and overwhelming weaknesses.
