A tip for taking notes with Diigo:
Go to J.otDown.com. Type a note and bookmark it to Diigo with a snapshot. You can then edit the note right in Diigo library by clicking "preview" under the bookmark's title, or go back to the note and edit it directly by clicking the its link. The changes will be saved in your Diigo snapshot and your j.otdown note automatically every few seconds. See the ? question mark in j.otdown.com for more info. Pretty cool!
