I came across a Firefox Add On called Diigo that enables you to mark up any page or article on the Web with notes and then share your notes with clients, staff, or any other group.
Once you download the Firefox add on, you can post sticky notes on any Web page and then save that annotated web page on a Diigo web server.
Then, you can create a group, invite members, and share your anotated web pages privately with them. If you want to make your annotations open to the public, it's even easier.
(In addition to Firefox, Diigo is offered as a Chrome add on and can also be used with Internet Explorer but does not have the same features as the Chrome or Firefox add-ons.)
View the two-minute video below to see the powerful benefits of Diigo annotations and then read a few key tips below.
Diigo enables deeply thoughtful collaboration and has many other features. It would be great if it were a bit easier to figure out.
Sharing your annotated Web pages privately is not explained well. Diigo user help falls short on this score.
One tip: The key to tapping Diigo's power for sharing annotations privately or with a group of people you invite is using the "Send" button in the Diigo toolbar.
When you click on Send, you'll see an option to "Get Annotated Link." That's where you can copy a link to an annotated page and send your notes. You can send the link by email or share it with any group you created in Diigo. See the screenshot below.
To make it easy for you to get started, I annotated a page and made it private and will give access to it if you join my group.
