Strongly Recommend: Use Diigo!
According to our surveys, many oD readers are involved in research in some form or other: as students or academics or media-folk or policy makers and influencers. So here is a recommendation that might well change the quality and usefulness of the web for you.
The best research tool I have come across in a long time - it has really transformed my web habits - is diigo.com, which gives me the ability to make notes as I read the web, to collect all my notes in one place and to share the notes with collaborators.
After joining, my recommendation is that you download and install the diigo toolbar - it makes adding notes and index-files of what you read very easy. It also has a number of other nice features that you'll probably end up using - for example, you can highlight a word and perform a Google search on it without any further typing, which I liked ...
Once you have joined diigo, make sure you sign up to the openDemocracy group on diigo. Joining the group will allow you to see the bookmarks and annotations from everywhere on the web of others who have chosen to share their notes with the openDemocracy group. You'll see when you create a note - the options are pretty clear.
Once you have signed up to the openDemocracy group, you can have a look at an example of the group annotation feature here where Anthony and I have commented on the UK Labour Party Deputy Leadership attitudes gathered by OurKingdom.
diigo.com is the web tool I use most. I have met with Wade and Maggie, the brains and business minds behind it - I feel they really understand what researchers need and are working hard to supply it. I really look forward to using diigo.com more extensively on openDemocracy and exploring various collaborative experiments using it. More later ...but in the meantime, do sign-up to diigo.com
