Tags help you find and organize your bookmarks by letting you select all of your bookmarks with a certain tag or combination of tags. Quickly add relevant tags to a bookmark by clicking on any of the recommended tags that appear under the description field on the “Save Bookmark” pop-up. When you are satisfied with the information in the “Save Bookmark” pop-up, click the “Save Bookmark” button. Now a link to the page is stored in your Diigo library, and the information you entered is stored with it.

Highlight Highlighting lets you denote important information on a page, just like highlighting in a book, but with Diigo, the highlighted text will be conveniently saved to your library as well. There are some important things for me to denote on my recipe. My wife doesn’t like pineapple, my grandfather can’t have eggs or chocolate, and I don’t like coconut very much, so I highlight those items on the recipe to let me know I need to deal with them. Highlight by clicking “Highlight” on the Diigolet. Then select the text you want to highlight. The text will be visually highlighted and the text is now stored in your library. It’s that easy. Click the button again to exit highlighter mode. You can also change the color of a highlight by clicking the downward-pointing arrow next to “Highlight” and choosing a color. Colors are useful for differentiating different types of highlights. I will use a different color for each of the different people I need to consider.

To add a sticky note to a highlight, simply move your mouse cursor over a highlight. When the little pop-up tab with the pencil on it appears, move the cursor to it and a menu will appear. Choose “Add Sticky Notes”. Now you can type and post a sticky note just like before, but this time it will be tied to the highlighted text.

Use the “Save” option to bookmark a page. Bookmarking saves a link to the page in your online Diigo library, allowing you to easily access it later.

Highlighting can also be accomplished from the context pop-up. After the Chrome extension is installed, whenever you select text on a webpage, the context pop-up will appear, allowing you to accomplish text-related annotation. Highlight Pop-up Menu – After you highlight some text, position your mouse cursor over it and the highlight pop-up menu will appear. The highlight pop-up menu allows you to add notes to, share, or delete the highlight.

Sticky Note Click the middle icon on the annotation toolbar to add a sticky note to the page. With a sticky note, you can write your thoughts anywhere on a web page.

My Interesting Ways to Use series has been really successful. I measure their success in how useful they are to teachers and other educators in helping with professional development. I say “My” in the loosest sense of ownership really, as with all of the presentations they belong to us all. I just kickstart them and point them off in the right direction.

The same undemocratic underpinnings of Web 2.0 are on display at Digg.com. Digg is a social-bookmarking hub where people submit stories and rate others' submissions; the most popular links gravitate to the site's front page.

While both sites effectively function as oligarchies, they are still democratic in one important sense. Digg and Wikipedia's elite users aren't chosen by a corporate board of directors or by divine right. They're the people who participate the most. Despite the fairy tales about the participatory culture of Web 2.0, direct democracy isn't feasible at the scale on which these sites operate. Still, it's curious to note that these sites seem to have the hierarchical structure of the old-guard institutions they've sought to supplant.
