Definitely a good portable tool: notes can be shared with the help of Dropbox. However, what really makes it attractive for bloggers is the tagging feature and automatic URLs saving.
Fantastic program. Can't say enough good things about it. Great design. Ultra ergonomic. Runs in the background. Simple, effective, rock solid. CintaNotes would be worth ten times the asking price. Not affiliated, BTW. Just like to do what I can to publicize good programs.
