Diigo - a hidden gem

If you use del.icio.us for online bookmarking and like google's notepad for online research, then suggest that you take a look at Diigo's offering. It's all those rolled in one and then some.

I've been using it for quite some time now (after trying out del.icio.us and google notepad) and I'm not budging! Recently I was doing a bunch of research online and diigo excelled!

1. Online bookmarking - will also simultaneously post to your del.icio.account


2. Firefox toolbar


3. tagging


4. Web clipping


5. Web annotation

Now to "hidden" - I've been on Diigo more than 8 months or so now - and yet I'm still to meet someone who knew about Diigo!!
Diigo rocks!
