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.
This is a really cool notes manager that has more features than most. It works by allowing you to clip text from any browser or app that allows copy/paste while providing a source link to the original information. There is a tagging system for organization, multiple PC and device syncing, and it can run from a flash drive. It also has an on board search system with predictive text to find notes quickly.
