#1: As you surf the web, bookmark resources for later use, adding specific tags for easy retrieval. Yes, any bookmarking service can do as much, but integrating your bookmarks with Diigo's advanced capabilities makes them much more useful to you. Want to keep using another service? Diigo can simultaneously bookmark to many other popular sites and your browser's Bookmarks folder.

#2: Highlight significant passages on each page to quickly locate them later. Take notes, right on the page, for later reference or to share your thoughts with others. Never again print out pages just to take notes, or shuffle through stacks of paper to find your notes again. Worried about "overcrowding" on key pages? While you can view all public highlights and notes, you can also limit your viewing to just your own, or to items left by members of one or more of your Groups.

#3: As you build your lesson plan, tag each resource by unit or by week, highlight passages you want to draw students' attention to, and add your own notes to guide them. You can also 'chain' resources by simply adding a link to the next page at the bottom of each note. Diigo's flexibility gives you freedom to use just the structure that is right for your needs and the needs of your classes.

#4: Save time while discovering useful new resources. Join Groups of others interested in the same subjects to exchange ideas and useful resources. Or, explore what your "interest neighbors" as suggested by Diigo have saved. Either way, you're sure to find resources you can use, without the trouble of hunting for them yourself.

#5: When you do need to search for a particular item, the Diigo toolbar simplifies the job. Multiple search engines are organized by category, and you can add your own search providers and categories, or reorganize existing ones in whatever way makes the most sense to the way you work. With all the best search tools right at your fingertips, it's easy to do thorough research.

#6: Hate photocopying and assembling bulky, wasteful handouts? Save time and money. Just tag the pages, including highlights and notes, you want to include, then quickly Extract all the information under that tag. Give students CDs containing copies of the HTML file which has links to all the original pages and includes highlighted passages and your notes, or print copies as you need them. Watch this demo to see how it's done.

#7: Keep up with changes, and always offer your students the latest, most accurate information. By finding frequently updated academic or educational sites on the Web, you can provide them with the most current and relevant material. All you need to do is delete links that have become useless, add the new ones you want, and when you extract the entire topic everything will be up to date.

#8: Provide feedback to your students in 'invisible ink' so you can avoid stifling their creativity. You can also create a Group to allow your students to pool resources and conduct discussions in private. Or, encourage them to interact with other students around the world. Diigo lets you do whatever's best for your class.

#9: Share anything you find with a colleague, including your highlights and notes, even if they don't use Diigo. Simply use the Forward feature, and Diigo will send anyone you choose a link to the original page along with the text you highlighted, your notes, and any comments you choose to add. All with no cutting, pasting, or going to another window to compose an e-mail.

#10: Use Diigo to help teach your students the digital literacy they'll need in the future. It is so well adapted to research, even college professors are recommending it to their students as an essential tool. And, it's so well designed students actually enjoy working with Diigo.

#11: Whether you write a blog for colleagues or to keep your students infromed, Diigo offers several useful features. You can blog directly from the Diigo toolbar, with a link to the page you're writing about as well as your highlights and notes already added to the post. Diigo will also send a linkroll of resources you've saved directly to your blog with no extra effort on your part.

#12: What if you're talking with a colleague or a student, and you'd like to share your resources about a particular topic on the spur of the moment? Just jot down a URL with the pattern www.diigo.com/user/yourusername/topic_tag and anyone with that link can access whatever you've saved publicly on that topic.
