If you haven’t heard of Diigo yet, it’s high time you took a look and made use of what they have to offer. They define themselves as a powerful research tool and a knowledge-sharing community. I believe their promise is backed up by the features they offer: bookmarking, annotations, clippings and the possibility to share everything you come across with others.

Diigo is not your average social network. Given its strong focus on effective research, most users are there to keep tracks of the domains they’re keen on. Unless you are able to create tons exquisite content on quite a few hot tags of Diigo, just bookmarking your own articles won’t get you very far.

So what other ways are there to use Diigo as a traffic generator?

I admit that I don’t use all these features; I still end up mostly using Diigo as my personal research tool. Having the ability to highlight and annotate text makes it much more useful as part of my personal learning environment than delicious. Personally, I think Diigo just looks a lot nicer than the barebones interface for delicious, especially in this version.

In summary, Diigo’s new sidebar is well designed. It allows me to focus on my work while, at the same time, giving me access to Diigo’s knowledge community. Improvements to Diigo Groups has turned this aspect of the Diigo community into a powerful way to distribute and refine knowledge among a team. And Diigo’s “varying degrees of non-intrusiveness” approach to social networking has infused a level of maturity into the social networking world that has been sorely lacking up to this point. There’s a lot of hype around Diigo right now, and the bottom line is that it’s well-deserved.

Diigo seems to be a mashup of many of the best features of del.icio.us, facebook, tumblr and twitter. You can save bookmarks, share them with friends and with groups, join groups, send each other links and messages and comment on your friends' walls.

Diigoは、まぁ「（ソーシャル・ブックマーク＋アノテーション）×共有×コミュニケーション」みたいなツールなのです。同様のことが、はてなブックマークやらはてなスターやらでもできるわけですが、洗練度はDiigoのほうが上だと思う。

Have you wished you could mark up a website? Highlight, add notes and the share it with others? Diggo is a solution to all your needs. Ok I exaggerated, it doesn’t have ink support (damn). However it lets you highlight, annotate, tag , bookmark, blog and share webpages. Isn’t that awesome? If you are tired of printing all those webpages to OneNote just so that you could highlight up the important parts, Diggo is your solution. Sign up, don’t hesitate to download the firefox/IE tool bar, give it a spin and well leave me a note of thanks :).
