Before I had started this module, I had heard that Delicious was a great bookmarking site. But after reading '10 Reasons To Use Diigo', I decided that Diigo was the way to 'go'. http://www.ictineducation.org/home-page/2009/11/2/10-reasons-to-use-diigo.html
I installed Diigolet so I can quickly bookmark, highlight, read later, share and place sticky notes on sites I am interested in. Bookmarking, like Google Docs, is another collaborative platform that makes searching for relevant websites very easy and again, a huge time saver.
In the classroom it cuts down on all the wasted time students spend looking for sites they have previously used.
