Rob and Paul, and others, suggested I check out MarsEdit for blogging.
If you are reading this ... then it worked! The software looks and feels very nice.
I've also picked up TextMate as my text editor. The evidence was overwhelming. Andy Hunt rather kindly comped me a copy of (the excellent) TextMate: Power Editing for the Mac and said it was the first editor to draw him away from vi in 25 years.
I've even started programming again ... in a small way. I've been working through Chris Pine's Learn to Program although I've been using it to RE-LEARN programming and pick up a little ruby. It's a great little book. Nicely, written; easy to follow. And Ruby ... wow, things have changed a lot in the 10 years since I last coded (in "c" and Cobol ... at the same time!). I'm really, really impressed.
