ScribeFire comes in two versions -- ScribeFire Notes, initially designed for enGadget whose editors wanted "a tool just for taking notes and text-editing." Notes uses the ScribeFire base without the blog-specific features. The full ScribeFire Blog Editor adds several features including direct blog posting. I first tried the Notes version and liked it so much that I moved up to the Blog Editor.
ScribeFire is very intuitive -- a top requirement on my list. The note window closely resembles the Blogger interface and I had no trouble figuring out how to create a new note, format text, and insert links and images. ScribeFire supports several blogging services and platforms includes WordPress, MovableType, and Blogger. It also offers a blog advertising program that I have not investigated.
The overall note taking interface is different from Evernote and Springnote in that the note titles are listed in tabs along the top of the note window and in a list window on the right. It does not use a tree-format. The window itself is accessed by clicking on an always-present icon in the bottom bar of the Firefox window. A new note taking window pulls up from the bottom of the browser leaving the currently open page in view. I like the easy accessability and obvious commands. Each of the three programs offers something different: collaboration, bookmarking, and sharing with Evernote and Springnote, and a free note-taking and blogging app with ScribeFire.
