If you browse or read a lot on the web, we believe you will find Diigo indispensable. Diigo is two services in one — it is a research and collaborative research tool on the one hand, and a knowledge-sharing community and social content site on the other.

A Personal Research Tool

Diigo provides a browser add-on that can really improve your research productivity. As you read on the web, instead of just bookmarking, you can highlight portions of web pages that are of particular interest to you. You can also attach sticky notes to specific parts of web pages. Unlike most other web "highlighters" that merely clip, Diigo highlights and sticky notes are persistent in the sense that whenever you return to the original web page, you will see your highlights and sticky notes superimposed on the original page, just what you would expect if you highlighted or wrote on a book!

Moreover, all the information — highlighted paragraphs, sticky notes, and the original url — are saved on Diigo servers, creating your personal digest of the web, your own collection of highlights from the web – ones that are meaningful to you! You can easily search, access, sort and share this collection from any PC or even iPhone.

A Collaborative Research Platform

Diigo enables effective collaborative research. You can easily share your findings, complete with your highlights and sticky notes, with friends and colleagues. A project team, a class, or a club can create a group on Diigo to pool relevant resources, findings and thoughts together.

A Social Content Site

With every Diigo user tagging and annotating pages online, the Diigo community has collectively created a wonderful repository of quality content, filtered and annotated by the community, on almost any subject you may be interested in. For example, if you would like to find popular resources on e-learning, searching Diigo can probably get what you want in less time than using search engines, and you may also gain insights from other users.

You can find and subscribe to the most recent or most popular bookmarks under any set of tags. Our system also provides recommended news and resources personalized to your interests.

While you are reading a web page, the Diigo sidebar shows you who else has bookmarked this page or this site, and what other similar pages and sites they have bookmarked, providing you a social browsing experience and a great way to find related content.

A Knowledge-Sharing Community

Since you are what you annotate – bookmarks, tags, annotations are a great expression of one's interests and expertise – Diigo provides new ways to connect and keep in touch with friends, and to learn both from your friends and about your friends with little extra effort.

Diigo also provides new ways to connect with others who share similar interests. You can find "people like me" – those who are closest to you in interests, or search people by tags or sites to find others who share certain specific interests with you. Once you find people of interest to you, you can connect with them in multiple ways: invite them to add you as a friend, send them messages, invite them to a group, or simply add them to your watchlist.

Diigo in Education

Diigo is an effective tool for teaching as well. Diigo's features allow teachers to highlight critical features within text and images and write comments directly on the web pages, to collect and organize series of web pages and web sites into coherent and thematic sets, and to facilitate online conversations within the context of the materials themselves. Diigo also allows teachers to collaborate and share resources among themselves.

Diigo is much more than a simple web annotation or social bookmarking service — it is a new kind of online research and collaborative research tool that integrates tags and folders, highlighting and clipping, sticky notes, and group-based collaboration, enabling a whole new process of online knowledge management, learning, and teaching in the information age.

It’s very good tool if you need to ask your students to read, highlight summarise or make an analysis of the text. It also gives you chance to provide more organised feedback to your students. You can save bookmarks and they can be accessed by multiple browsers.

However sometimes changes made doesn’t save at all. You can find some of the items (bookmarks etc.) are missing or there’s no option to see the list of tags. An app also fails on mobile, unfortunately.

I teach Information Technology and the Basics of Computers to 1st year students. When it comes to saving things on "Favorites" I always make a note to tell them about Diigo, stressing that their Favorties will only be aved on the computer in the lab. With Diigo however they can check their bookmarks anywhere.

Diigo is a really useful tool. I haven't actually used it to its full potenial. There are many sharing options that I haven't used. Nevertheless, it makes surfing the internet really stress-free. You may be reasearching one topic, only to come across something different but useful. You can bookmark it, adding a tag, or adding to a list for later. I would be lost without it.

There are also times when I don't need to do anything more than log into my diigo account when something comes up in class and I can find a website to share in no time.

I used to use Delicious many moons ago, but since I came across Diigo I'm a convert. I once read somewhere (I can't remember where, my apologies to the author) that "Diigo was like Delicious on steroids". I agree, you can o so much more with it. You can bookmark and website and add multiple "tags" so you can quickly find relevant information on any topic, you can create your own lists (e.g., for a specific topic, or class), you can create your own groups so you can share specific resources with specific groups of people (e.g., different classes). You can add sticky notes and comments that others in your group can see. Others can comment on your bookmarks. In groups, you can set permission about who can add bookmarks etc. etc.

I use this tool with most of my online (& on-campus classes). I start a class group and provide students with instructions about how to join the group. Anyone can see the bookmarks but only group members can comment and add bookmarks. My teaching focuses on integrating technology in the classroom When I add resources to the group, students receive an email advising them a new resource has been added. I encourage students to add their own resources to the group. However, unless I make it a compulsory assessment task most do not add anything. I do get lots of comments from students on the resources I add which indicates they are looking at them. I am also thinking of using it as a "recommend reading list" as you can set the option to add new bookmarks under the existing ones. Therefore my original recommended readings will always be at the top and "additional readings" can be added below – by any group member.

Yes, I have recommended this tool to colleagues.

I used to use google bookmarks, but they never developed it. After a little online review comparison with sites like tumblr, and delicious, I settled on diigo. I can only speak to the free version. Like any other bookmarking site, your bookmarks are available to you wherever you go. I particularly like the ability I have to mark things as 'read later.' This allows me to bookmark, but not read in the moment when I have less than full attention available. Diigo is social too, though I have yet to take advantage of it. I added powernote to my android phone and can bookmark anything from my phone. I can also take notes on my phone through powernote that will be stored in my diigo bookmarks.

I love being able to take notes on a given site directly onto the site itself. They are there when I return. I have not used this with students, but can see major potential here. I can make the notes public or private. I can send links directly from within diigo to friends through many different communication channels. This is a powerful tool and I am not even using half of its capabilities.
