Although a site like SuperUser or Quora (http://www.quora.com/What-is-the-best-blogging-software-out-there http://www.quora.com/What-is-the-best-blogging-software-out-...) might be better suited for this question, I'll weigh in and say your wife should try Squarespace.com and WordPress.com and see which one better suits her liking. If WordPress feels more right, then she has a plethora of options before her (from Tumblr to self-hosted WordPress). If Squarespace feels better, she should just stick with that.
