I've been using the social bookmarking site del.icio.us for a long time. One thing I've never really done was use the notes feature on the bookmarks because I didn't want to take the time to write the note. I would tag it as I wanted and move on. Today I discovered by accident that if I highlight a section of text on the page I'm going to tag with my Firefox del.icio.us add-on it will automatically import that text into the notes field. Maybe this is common knowledge to del.icio.us users but it wasn't to me. I think it's fair to say I'll be using the notes feature a lot more from now on. It's a great little shortcut.
