Remember how happy and excited I was when Wikalong, an early social Web annotation tool, came out? How I wrote excoriating notes about the royal family in a sidebar to the Buck House Web site that everyone else who had the Firefox Wikalong extension could read and edit? And how Wikalong died in the water because using it was, frankly, purgatory?
A quick review of Web annotation tools threw up various sticky notes software which work with Firefox browser button add-ons. MyStickies and Sticki had their limitations though – they interfered with the flow of the page, and were not specifically enough positioned. Diigo is still the best. Diigo can highlight, add sticky notes, tag, bookmark (simultaneously to other online bookmarking accounts too), clip, aggregate clippings, and manage groups. You can make your work public (though they ‘raised the bar’ to avoid ‘littering’ – you have to have two invited friends with accounts), private and/or collaborative. TechCrunch reviewed Diigo last summer.
I’m finding it particularly useful for annotating contributions in blogs and discussion groups, as well as Web sites in general. You can make the important passages salient which is a great help if you are a tiny bit dyslexic and/or have a sieve brain.
