Make way, Del.icio.us! Diigo is here, and it's changing the way people use and, in true Web 2.0 fashion, interact with the Internet.

If you like del.icio.us, you will love Diigo.

I will not be the first to say it, but Diigo is like del.icio.us on steriods. Diigo bookmarks your favorite sites, uses tags to classify your bookmarks, allows you to make bookmarks private or public. It can even automatically post your latest saves to your blog.

But Diigo provides innovative ways to interact with web sites.

Diigo lets you highlight text on a page and annotate it with sticky notes. As a PhD student in the 21st century, this innovation frees me from downloading and re-reading sites I use for my research on the internet. I use less paper and I save time.

Diigo also makes it more-than-easy to email a web site to a friend. I like Google Reader for the same reason, but Diigo out-shines even Google Reader. Highlight the text on a page that you want your friend to see and that text will be included when you email the page to them. Eliminates the "Huh? Why did she send me this link?" problem.

I generally shy away from using any service that requires me to download a tool bar, but the Diigo tool bar earned its keep quickly. The tool bar not only provides quick access to your Diigo dashboard, bookmarks, lists, groups, and contacts, but also makes for easy bookmarking, highlighting, commenting, and sending.

It's been called a supercharged social networking tool, a cut above del.icio.us, and "Diigo" has even been used as a verb. Even though I know I haven't discovered all the features, it's changed the way I interact with web pages.

it has a lot more features than my current favourite, del.ico.us:

- Longer description when bookmarking pages.
- Saving bookmarks to Twitter (if you are into that!)
- Web links can be automatically saved to del.ico.us and 3 other social sites.
- Instant bookmarking of a web page (one click save)
- The toolbar has an icon which shows whether the site has been bookmark previously.
- Bookmarks can be tagged read/unread status
- There are highlighting and collaborative features like sticky notes and site comments/
- You can import from other social bookmarking tools (del.ico.us, magno.lia.com, furl, etc)
- Images can be clipped and saved.
- Embedded videos can be captured and saved (supporting youtube.com, myspace.com, video.google.com, video.yahoo.com, atomfilms.com and many others)
- You can send bookmarks to major blog platforms easily (one of my favourite features)
- Cached feature: archive of the original bookmarked webpage can be accessed
- Diigo's Site Communities aggregate users who bookmark & annotate the same website & build meaningful reader communities.
