It is great for research. Say you are researching a topic, and you come across a paragraph that has a definition or other information you want to save. But it's buried in a whole long page of material. How will you find it again?
Notefish lets you set up separate, private pages (though you can share them -- but they're not just open to the public) where you can save snippets of web pages.
You have to do 2 things:
- Register for Notefish
- Download and install the Firefox add-on. Actually, once you've downloaded it, it will prompt you to register, I think.
