Your points are well taken.

Regarding #1, a feature like that will be out in a few days.

#2: check out our group feature.

#3: soon.

Things I don’t like about Diigo as an annotation tool:

First, the Forward option should include the ability to just copy the appropriate URL. That I have to expose someone else’s email address or send it to myself to get the URL doesn’t respect the user’s time/convenience or his/her wish to maintain the privacy of friends’ email addresses. I don’t WANT to send their email addresses through Diigo’s servers.

Second, because the Private/Public options are two extremes with no options in-between. Either your annotations are available to all, or only to you. The fact that I can’t decide with whom to share it is another limitation.

Third, the annotated page neither immediately scrolls to the annotations (like CiteBite) nor provides navigation for annotations (like SharedCopy).

Regardless, thank you for pointing this feature out to me. I haven’t looked at Diigo in a long while, and it was interesting to see how it has grown.

True. And I like the way Trailfire can take a user on a tour of URLs in deliberate sequence- but it sure is slow for me.
