how about using a tag to trigger a sync:in diigo:add the tag "zotero" - you can then manually (?automatically) ask zotero to check whether it has already added "zotero" tagged items. It can also pull down comments into zotero notes, sync the other tags, and add a link back to the diigo page.in zotero:add the tag "diigo" This would cause a new diigo bookmark to be created, including addition of annotations from zotero notes.the difficulty would be in keeping track of which note in zotero corresponds to which annotation. A one-off copy would not be very good. Maybe include a unique code with each note (ugly), or use a fuzzy match so updated annotations are recognized, providing they have at least a few words in common.
