Diigo is by far the best annotation service available. Highly underappreciated and overlooked.
Seriously becoming one of the most efficient research tools I've used.
i'm curious how this relates to what the team at Genius is trying to do in terms of annotating the world. cc @dumbnamenumbers
I've always loved Diigo. It does some really nice things that Evernote does not do well. Love the UI.
Really great tool, I am also surprised it doesn't get much interest.
